The alphabet network has announced the return dates of Rookie Blue (season three), Secret Millionaire (season three), Wipeout (season five), Bachelor Pad (season three), and Extreme Makeover: Weight Loss Edition (season two).

THE BACHELORETTE – PREMIERES MONDAY, MAY 14 (9:30-11:00 p.m.) Emily Maynard, the beautiful, sweet, young mom who captured America’s and Brad Womack’s heart on the 15th season of “The Bachelor,” finally thought she had her happy ending. She accepted Brad’s proposal but unfortunately their relationship ended, along with her dream of moving to Austin with her daughter, Ricki, and starting a family. But Emily, 26, is ready for her luck to change and to bring her the love she so richly deserves. It’s hard to meet men as a single mom, but Emily will have her pick of 25 bachelors when she gets a second opportunity to find love starring in the eighth edition of “The Bachelorette.” Instantly popular with “Bachelor” fans, Emily’s strength, passion and southern charm – as a mother and as a woman – would make anyone happy to make her his wife. She feels incredibly grateful to have found her first love when she was very young, although her fiancé, famed NASCAR driver and team owner Ricky Hendrick, tragically died in a plane crash. She then discovered she was pregnant with their child, the apple of her eye – Ricki. Despite not having dated a lot, Emily knows what it’s like to be truly in love. In the past seven years, she has been looking for someone with the same spark she has for life, and she believes that she will find her soul mate on “The Bachelorette.” Chris Harrison is the host. “The Bachelorette” is produced by Next Entertainment in association with Warner Horizon Television. Mike Fleiss and Martin Hilton are executive producers.

DUETS – PREMIERES THURSDAY, MAY 24 (8:00-10:00 p.m.) “Duets” is a one-of-a-kind singing competition that takes the Superstars out from behind the judges’ panel and onto the stage. Kelly Clarkson, Jennifer Nettles, Lionel Richie and Robin Thicke set out on individual journeys across America looking for undiscovered talent worthy of being their protégés. Ultimately, each Superstar will choose two singers for their duet partners, and together the Superstars and their protégés will take the stage each week and perform in front of a live studio audience. In the end, only one duet will be at the top of the charts, and the winning amateur will receive a recording contract with Hollywood Records. “Duets” is a production of Keep Calm and Carry On Productions. Emmy winner Robert Deaton (“The CMA Awards”) is executive producer. Emmy winner Charles Wachter (“Jamie Oliver’s Food Revolution”) is co-executive producer.

ROOKIE BLUE – PREMIERES THURSDAY, MAY 24 (10:00-11:00 p.m.) A group of young and ambitious rookie cops continue to navigate the emotional trials and tribulations of their professional and personal lives. After two years on the job, these rookies are well on their way to becoming experienced cops, but at what cost? What price will they have to pay, both professionally and personally, to succeed at their job? And how can they stay true to themselves – maintaining their individuality and compassion — along the way? While a new rookie — ex-soldier Nick Collins, who is trying to adapt to policing after serving in Afghanistan — has joined 15 Division, the rest of the rookies are now entering their third year on the job. They have overcome the sophomore curse — that a little knowledge is a dangerous thing. However this year the rookies of 15 Division are going to learn to be careful what they wish for – and they’re going to learn it the hard way. Emmy Award winner William Shatner (“Boston Legal”) guest stars on the premiere as Henry McLeod, a belligerent drunk driver with a haunting secret. “Rookie Blue” stars Missy Peregrym as Andy McNally, Gregory Smith as Dov Epstein, Charlotte Sullivan as Gail Peck, Enuka Okuma as Traci Nash, Travis Milne as Chris Diaz, Peter Mooney as Nick Collins and Ben Bass as Sam Swarek.

SECRET MILLIONAIRE – PREMIERES SUNDAY, JUNE 3 (8:00-9:00 p.m.) “Secret Millionaire” follows 13 of America’s most successful business people as they spend a week in the country’s poorest areas and ultimately gift deserving members of the community with hundreds of thousands of dollars of their own money. Originally based on the hit UK series of the same name, each episode follows one of America’s most successful business people for one week as they leave behind their lavish lifestyles, sprawling mansions and luxury jets, conceal their true identities, and go to live and volunteer in some of the most impoverished and dangerous neighborhoods in the country. Surviving on welfare wages, their mission is to discover the most deserving individuals who continually sacrifice everything to help those in need, and ultimately encourage others to do the same. Throughout this incredible, life-changing experience, the Secret Millionaires will attempt to remain undiscovered, coming face to face with extraordinary people battling the odds every day of their lives. On the final day, in an emotional and dramatic climax, they reveal their true identities. Ultimately, the millionaires will each give away a great deal of their own money, changing lives forever and encouraging others to keep giving back. “Secret Millionaire” is executive-produced by Claire O’Donohoe, Grant Mansfield, Natalka Znak and Leslie Garvin. Paul Osborne is co-executive producer. The series is a Zodiak USA Production.

EXTREME MAKEOVER: WEIGHT LOSS EDITION – PREMIERES SUNDAY, JUNE 3 (9:00-11:00 p.m.) The hit series returns for Season 2 as transformational specialist and bestselling author Chris Powell documents the amazing makeover of eight courageous, “super obese” people who, in an unprecedented 365 days, set out to safely lose half of their body weight, ultimately revealing an amazing metamorphosis. In each of the eight stand-alone, two-hour episodes, the participants, whose ages range from 19 to 50 years, undergo a transformation not only of their bodies, but of who they are as individuals. By assuring that the participants have the proper nourishment and exercise movement, Powell provides a fresh perspective to individuals whose lives have become unmanageable because of their weight. He guides each of the eight participants through their transformation process by moving into their homes with their families or loved ones. The upcoming season is filled with remarkable and eye-opening changes, including one participant who loses 50% of his body weight, despite being homeless for most of the year. Another loses a staggering 142 pounds in the first 90 days, while still another will lose a grand total of 281 pounds over the year. In a show of support, one participant’s family challenge themselves to lose 500 pounds together. In 2012 Chris Powell became a bestselling author when his Hyperion book, Choose to Lose, hit No. 2 on the New York Times Bestseller List.

Hosted by Fred Willard (“Best in Show,” “Modern Family”), featured celebrities include David Hasselhoff, Ricky Gervais, Jerry Springer, Florence Henderson, Jack & Kelly Osbourne, Jane Seymour, Serena Williams and Mark Cuban. The exciting new format finds each celebrity reminiscing about key episodes that have happened in their lives, then brilliant improvisers acting out those moments which the celebrity has just described.
