It's not a threat or a warning, be careful with Cardi B. The "Bodak Yellow" rapper might be pregnant with her first child — but that's not stopping her from defending herself. Cardi got into a huge screaming match with a fan inside a Las Vegas mall — and if her security wasn't there, things may have turned physical.

It all started when Cardi B (real name: Belcalis Almanzar) refused to take a selfie with the woman, who has been identified as Lolita Beckford-Dawkins by The Blast. According to the instigator, she bumped into the former Love & Hip Hop star as she was leaving the Fendi store in the Vegas shopping center. Cardi allegedly ignored the woman and her friends when they asked for her picture and that's when Lolita screamed, "F–k Cardi, you ain’t s–t!"

Cardi, 25, allegedly explained that she did not like the way she looked (you know, being that she was very pregnant at the time of the altercation) but Lolita believes she was being "fake." That's when the back and forth started, but Lolita, who is a mother of five, is adamant she would never hit a pregnant woman. Right… you would just make her feel bad for not wanting to take a selfie.

Fans were definitely on the hip-hop star's side side when the video of the fight surfaced. "Unreal how DISGUSTING people can be," one user commented on Baller Alert's Instagram post. "She is on no way obligated to oblige these stalker psycho so-called fans." Another added, "Love how these 'FANS' resort to calling her a b—h when they don't get what they want. Fake ass b—hes, leave her alone she be HEAVILY pregnants. Jesus."

Luckily for Cardi, a glass window separated the two women — and eventually she enjoyed a private shopping spree inside the designer store. OKKUUURRRR. More recently, Cardi B's bodyguards were accused of beating up another fan who wanted a selfie outside a Met Gala after party, but Cardi, who was with her boyfriend Offset at the time, insists it was for her protection. "If you check my tag pics I take a lot of pics with fans. Some people are not fans and sometimes I don’t want no pics and I simply don’t want people too close cause of [my pregnancy]," she wrote on Twitter. "I don’t know what are people’s intentions sooo I be careful. Why can’t people respect that?"

Preach.
