Former Destiny's Child singer Kelly Rowland dropped 70 pounds just four months after giving birth to her baby son Titan.

Rowland revealed her secret to Extra giving credit to SoulCycle.

"Jeanette Jenkins is the secret, SoulCycle is the secret, Angela Davis," Rowland told Extra's AJ Calloway.

"When I go in there and it's the wee hours of the morning she is a great secret, so motivational. Jeanette comes in with so much energy and this huge smile on her face and you can't help but to get excited about working out."

The 34-year-old singer also shared some secrets about eating saying that it's okay to munch on some fatty foods sometimes.

"The 80/20 rule is all the way real, 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 said.

Rowland and husband Tim Witherspoon welcomed their first child together back in November, Billboard reports.

The star also talked about how reuniting with Destiny's Child is not always about business but just old friends catching up.

"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," she said.

"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."

Rowland recently had a special performance honoring the City of New York Department of Sanitation, according to Page Six.

About 100 workers were invited to the performance but only half were able to show up at Houston Hall downtown because of the snow storm on the first day of spring.

The "Dirty Laundry" singer said she is happy to be back in the study as she is enjoying her new journey in motherhood.
