Rapper Meek Mill has urged Nicki Minaj to leave him alone after she switched up a song lyric onstage and teased fans with "secrets" about her ex.

The Anaconda hitmaker was performing at the FOMO Festival in Australia over the weekend (05-06Jan19) when she changed a line referencing Meek in Barbie Dreams, a song in which she poked fun at rumoured love interests and other male rap peers.

On the tune, she claimed her former boyfriend was repeatedly direct messaging (DM) her on social media as she went on to reference their sex life, but on the revamped version fans heard Down Under, Nicki appeared to send her ex a little warning message.

"Meek still be in my DMs, I be having to duck him," she rapped, just like in the original, before dramatically halting the music and adding, "I could tell you secrets but I won't/Cause being a bitter b**ch is what I don't."

Shortly after the news of her lyrical change surfaced online, Meek took to Twitter and appeared to respond to the remarks, although he didn't address Nicki directly.

"Why you be sooo mad at me and not the people that came right at ya neck (sic)!" he wrote. "I'm cool I'm doing good lol (laugh out loud) something is wrong here."

Meek then suggested he had some of his own gossip to share about Nicki, continuing, "Leave me alone you know I get a lil too out of control with the truth (sic)!"

"Keep it classy," he concluded.

Nicki, who dated Meek for two years until their split in 2017, has yet to comment on his Twitter posts.

Meek previously insisted Nicki's Barbie Dreams line wasn't actually based on any truth.

"I ain't get no heads-up (about the song), but I definitely wasn't in nobody's DMs (sic)," he told Vulture last year (18). "And definitely wasn't nobody ducking me, s**t (sic). That's a fact."

She has since moved on to a new man, going public with Kenneth Petty on Instagram last month (Dec18).
