It’s only been four months since Kelly Rowland gave birth to her son, Titan, and she looks fabulous. Many are amazed at the singer’s transformation, while others are asking, “How did she do it?”

“The 80/20 rule is all the way real,” explains Kelly. “Eighty percent of the time you eat those foods giving you nourishment, you’re eating clean, and twenty percent of the time, have guacamole, a ton of it like I do, and a margarita and maybe queso too!”

Rowland also tells A.J. Calloway of Extra that she thoroughly enjoys being a parent. “I think the best part of being a mom, actually it’s being Titan’s mom,” shares the star. “Titan is a pretty incredible kid.”

Although she loves her son, Kelly also has an incredible passion for music. “I’m focused on the studio right now,” says the recording artist.”[I’m] getting a lot of inspiration from Paris fashion as well.”

As for a Destiny’s Child reunion, “The last reunion happened the other day when we all sat down and were just talking and enjoying each other’s company. It was awesome. Not every time you see Destiny’s Child together may be in front of the camera. We still have our bond amongst each other, that’s the most beautiful gift Destiny’s Child has given me.”

Titan is Kelly and husband Tim Witherspoon’s first child. He will celebrate his first birthday later this year.
