Former Destiny's Child singer Kelly Rowland is spilling the beans about her recent physical upgrade. The R&B diva admits to having breast enlargement surgery in October to transform her from an A-cup to a B-cup.

"I was sick of not fitting into my tops," she says in an upcoming issue of People magazine. "There was this one really hot House of Dereon top -- I just wanted to fill that out!"

Rowland has kept her surgery a secret up until now, and the singer admits she was reluctant to discuss her decision to go under the knife.

"It is a decision I made for myself. 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 explains. Read the full story.

In other Rowland news, rumors are swirling around the singer's possible forthcoming Playboy spread. According to YBF, the singer is in talks with the iconic men's monthly, known for splashing pics of women wearing nothing more than their birthday suits across its pages.

Reports claim Rowland is being offered $500,000-$1million to shed her clothes. A partially-nude or nude pictorial in Playboy could prove to be jaw-dropping to fans of DC's once semi-wholesome image.
