No nip and tuck here! Blac Chyna took to Snapchat to blast rumors that she underwent weight-loss surgery to get back in shape after giving birth to her daughter, Dream Kardashian.

As Us Weekly previously reported, the Rob & Chyna star, 28, was photographed with a noticeably smaller waist as she stepped out in Los Angeles on Saturday, November 19, after welcoming Dream with fiancé Rob Kardashian earlier this month. Later that day, Chyna took to Snapchat to show off her flatter stomach, which sparked reports that she might have had plastic surgery.

"So I posted a picture of my belly yesterday and the only reason it got that flat, you guys, is from breastfeeding and breast pumping and from my body already being small before my pregnancy," Chyna explained in a Snapchat video while pumping breast milk for Dream on Sunday, November 19.

The model then posted a follow-up clip of herself smiling, which she captioned: "Not surgery guys."

"If you are pregnant right now, I would highly recommend breastfeeding and breast pumping because it'll get your weight back down fast," she urged fellow new moms on Snapchat.

Chyna, who is also mom of 4-year-old son King Cairo with ex Tyga, recently revealed that she has lost a total of 21 pounds since giving birth to Dream via C-section on November 10. "Goal 130lbs my starting weight b4 Dream," she captioned a Snapchat post last week.

While working toward reaching her goal weight, the Lashed Bar owner has been spending plenty of time with her newborn daughter. On Sunday, Chyna shared an adorable video of King kissing his baby sister on the cheek via Dream's Instagram account. She captioned the post, "I love my big brother King."
