It’s a battle of the baby mamas. Masika Kalysha, who says she's pregnant with Fetty Wap's baby, appears to be feuding with the rapper's ex Lezhae Zeona.

It's not clear what started their war of words, but  Saturday both women took to Twitter to bash each other. According to The Shade Room, Kalysha posted a tweet taking a jab at Zeona, which upset her.

"My child's never coming to the hood to play with yours girl bye," the former "Love & Hip Hop: Hollywood" star posted.

Zeona, who shares a daughter with Fetty Wap, quickly fired back, writing, "My child's never coming to the waiting room at the plastic surgeons office to play with yours girl bye."

She added, "And Masika Michael Jackson looking a-- better watch her mouth I know Tf that. I do international pop ups #HelloLA."

Kalysha definitely didn't back down and sent another tweet calling Zeona a "bum."

“You bums talk s--- about me all day but I don’t say a bums name won’t give uu any fame," she wrote.

As previously reported, Kalysha has been in a nasty feud with her alleged baby daddy. In December the singer and reality star announced she was six months pregnant and said the "Trap Queen" rapper was her unborn child's father.

Fetty Wap, however, has repeatedly denied the baby’s his but admitted recently that he did have unprotected sex with Kalysha after meeting her at a party.

“I don’t really know how to explain that s---,” he told The Shade Room. “She knew what she was doing. I wasn’t no random dude in the club. She knew I was gonna be there. It’s a lot of s--- going on with that right now ... Congratulations to her and whoever is the [father].”
