She's set to make her first appearance on Saturday Night Live on Saturday, to coincide with her album release.
And Cardi B was doing nothing to quash pregnancy rumours as she performed a warm-up gig on Friday night.
The 25-year-old rapper wore a voluminous frilly dress to hide her figure, for the appearance at E11EVEN club in Miami, Florida.
The metallic off-the-shoulder puffy pink gown swamped the Bronx-native, fueling speculation she's expecting a baby with Migos rapper Offset.
The Bodack Yellow hitmaker, who has kept silent on the subject, sported a vamped up platinum hair-do.
The musician - whose given name is Belcalis Almanzar - certainly didn't have puffy ankles to worry about - showcasing her nicely turned ankles in vertiginous Christian Louboutin silver heels.
Her nails certainly didn't look ready to change a diaper any time soon, as they were fiercely long and pointed, with a metallic polish.
The star - whose debut album is aptly titled Invasion Of Privacy - has insisted she won't comment on the reports she's expecting a baby with her fiance.
The artist explained on Thursday why she was staying silent, telling people that they should listen to her upcoming album if they want to discover things she'd rather rap about than talk about, during an interview on Apple Music out Thursday.
Speaking to Ebro Darden, the starlet said: 'I feel like people just got to tune in a little bit on my album and they will know a little bit more because I can't address all the rumors and everything.
'I have been so open to people about myself. People cannot expect me to be open about everything. Certain things to me, it has to be private. You cannot invade my privacy,' said B ahead of her Friday album release.
Cardi - who became engaged to Offset in October last year - blasted the idea that she should be open like an 'animal in the zoo', and hinted that people would only know if she was pregnant 'if it [the baby] arrives'.
Speaking during an interview for Beats 1 Radio, Cardi said: 'I'm not a damn animal at the zoo that you just could see everything, no. People will just find out more. If it arrives, if it don't arrive, then you gonna know what the f**k is going on.'
At the beginning of December, 2017, Cardi B said that she and Offset plan to spend $1 million on their wedding.
