The singer also had a PDA moment with her beau, Offset, on the red carpet.
Cardi B knows how to shut down a red carpet.
The "Money" rapper was a total knockout as she showed off her toned abs at the 2019 Billboard Music Awards at MGM Grand Garden Arena in Las Vegas on Wednesday.
For the annual celebration, Cardi, 26, opted for a yellow, crystal-embellished halter top and matching ruched skirt with a thigh-high from Moschino by Jeremy Scott. The revealing look was bedazzled with various crystals and diamonds throughout. She completed the two-piece by wearing silver hoop earrings and silver strappy heels. Her hair was straight, down and parted down the middle.
With Cardi was her beau, Offset, who looked dapper in all black. The couple couldn't help but share some PDA moments while posing for the cameras.
This year, Cardi B leads the pack of nominees at the Billboard Music Awards with 21 nominations, and she will likely take home a slew of trophies.
Meanwhile, ET caught up with the mother-of-one who revealed she recently underwent cosmetic surgery. She said in a video posted to Instagram last September that she was planning to go under the knife after her daughter, Kulture, "did [her] bad."
"I just got my boobs redone," Cardi shared. "I feel good, but then sometimes I feel like not, you know? [When] your skin is stretched out."
