Welsh MPs and locals voiced their disapproval for the show yesterday, following a launch episode which included boob and bum flashing, lewd activities in nightclubs and candid sex talk.
Anna Kelle, known as AK, appears on the series as a mentor for the wannabe models and musicians who have left the Valleys to live together in Cardiff. The 31-year-old glamour model insisted that none of the young cast members did anything wrong in the first episode.
"They're kids having fun," AK told Newsbeat.
"I'm 31. At 16, 17, I got my bum out, flashed my boobs, who hasn't?
"If they haven't, they're boring. Life's about being kids, living life and having fun.
"They're having fun and they're working hard. So what if there's bum flashing. They're jealous."
Meanwhile, cast member Nicole Morris argued: "It's not for old people, for nanas and stuff. If you've got a bum like me, let me tell you, it's banging, so get it out. You're not going to get it out when it's wrinkly."
The Valleys airs on Tuesday nights at 10pm on MTV.
