The "B" is for belly! This week, Cardi B admitted that her abs aren't as flat as she'd have you believe. On Tuesday, the rapper shared a thirst snap that shows her posing on a pool lounger in a string bikini. In the caption, she told fans, “I suck the s**t out my stomach for this pic." She followed that confession with a video a few hours later in which she dared to flaunt her stomach flab. In the clip, a bikini-clad Cardi B walks toward the camera as a wrap falls off her hips. She then turns to the side to show off her silhouette before un-sucking her midsection. She captioned the video, "Suck it in life." [Us Weekly]
