As for the one-cup upgrade, Rowland says: "I didn't want to have double Ds and be a little bitty size 2 - that would look nuts!"
The 27-year-old singer went under the knife after a long decision-making process.
"I was sick of not fitting into my tops," she says. "There was this one really hot House of Dereon top - I just wanted to fill that out!"
Rowland says that top - designed by Beyonce's mom, Tina Knowles - complements her new curves: "I put it on and I looked so good! I'm so happy. I feel complete."
Rowland, who has released two solo albums, says she hesitated to discuss the surgery.
"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)," she says.
