YBN Almighty Jay, born Jay Bradley, announced the news in a since-deleted post Tuesday on Instagram Stories.
"@blacchyna & I Are No Longer Together," the 18-year-old rapper wrote, according to People.
Entertainment Tonight confirmed Blac Chyna, 30, and YBN Almighty Jay "very recently" called it quits.
"She's doing really well. She is focused on her children, her health and her fitness," a source said of Blac Chyna, who is parent to 5-year-old King with Tyga and 19-month-old daughter Dream with Rob Kardashian.
Blac Chyna and YBN Almighty Jay were first linked in February after they were spotted getting close on a bowling date.
Fans speculated this month the pair were expecting their first child together, although TMZ later denied the reports.
