Former Destiny's Child singer Kelly Rowland just wanted to fit in ... her cute clothes.

The singer-actress reveals that she had plastic surgery last October to increase her "A cup to a B cup," reports People.

"I didn't want to have double Ds and be a little bitty size 2," says Rowland."That would look nuts."

It was clothing from House of Dereon, the clothing line designed by Beyonce Knowles' mother Tina, that clinched the decision.

"I was sick of not fitting into my tops. There was this one really hot House of Dereon top. I just wanted to fill that out," says Rowland about her reasons for the augmentation. "I put it on, and I looked so good. I'm so happy. I feel complete."

Despite her decision, Rowland doesn't think going under the knife is the answer for everyone.

"It is a decision I made for myself," she explains. "I like it, and that's all that counts. For young people: Think about it before you just jump off and do something [you may regret later]."

Rowland, 27, released her second solo album last July with "Ms. Kelly." She's also crossed into the acting field with 2003's horror franchise crossover "Freddy vs. Jason" opposite Jason Ritter and Monica Keena. She's also appeared on the small screen, making guest appearances on "The Hughleys," "American Dreams" and "Girlfriends."
