Iggy Azalea has gone on another rant at her ex-boyfriend Playboi Carti after accusing him of cheating on her. She brand the rapper, 24, "manipulative" and accused him of using their five-month-old son Onyx as a "pawn" in their relationship. The Fancy singer, 30, had previously claimed that her baby daddy had chosen to party with "a mistress" instead of being there for Onyx's first Christmas last week. In a new set of posts made to her Instagram account over the weekend, she decided to criticise him again.

"A baby is not a pawn! Shall I continue?" her first post said. She added: "It's the lying to me for no reason that upsets me."

Iggy said Playboi had "manipulated me via my own child and has had full access to his child since birth". The mum-of-one then addressed two women she believes Playboi cheated on her with. She went on: "You both were already in the mix in December while I was five months pregnant and you very much knew that this man had a full girlfriend, lived in a house with her and was having a boy. Y’all both knew that."

Iggy also accused them of leaking her pregnancy news to the media before she announced it.

She said: "Please stop f****** lying trying to clear your name as if this s**t is kosher and you didn't know any f****** better because I will keep pulling receipts."

It comes after Iggy claimed Playboi decided to change his Christmas plans last minute, and threw a release party for his new album, Whole Lotta Red. Iggy tweeted: "I would never decide to do something of my own free will that meant missing a milestone moment with my son and if you do you're trash." Too bad you got an album out but can't even come to Christmas with your own son. Imagine not flying out your family on Christmas but you have the girl you cheated on my entire pregnancy at your album party and magically me and my son can't come for Christmas anymore? TRASH."

She went on: "This man had a whole family vacation planned 48 hours ago and I hope this message gets to you, girl. Although you hid in a whole closet from my housekeeper so it's not like you have any dignity I guess. To clarify this man was literally at my house last night telling me he loves me. So, this is very much NOT me being bitter, it's me not ducking with trifling a** shit that happens at the expense of my son."
