Rumors that Cardi B is pregnant with her second child are growing stronger and stronger. MTO News reported that people in Cardi's inner circle are openly speculating that Cardi and husband Offset are expecting their second child. 

For the second time this weekend, Cardi hid her stomach from her fans, during a public appearance.

On Saturday night, Cardi performed at the Palms Casino in Las Vegas. Instead of her usual revealing outfit - Offset's wife wore an outfit the covered her stomach.

But that's not all. The paparazzi managed to catch up with Cardi when she was in Vegas. She was seen walking the casino in a bath robe, and holding her belly.

If Cardi is indeed pregnant, this would be her second child with Migos rapper/husband Offset. They already have a beautiful daughter Kulture together.

According to TMZ, Cardi B has come a long, LONG way since dropping her debut album last spring -- so if the woman's a little late to a scheduled speaking gig, so be it ... folks will wait for her.

The "Money" MC showed up a few hours behind schedule Sunday to the Beautycon Festival in NYC, where she was set to speak on a panel about "money moves" and the keys to success in the beauty world. Apparently, Cardi had people waiting for a good 3 to 4 hours.

She eventually showed though, and looked great as usual -- wearing a fur and wide-brimmed hat with matching heels. CB talked about success ... and she's had a lot of it lately.
