A rep for the 'Dip It Low' singer has confirmed to Us Weekly that she's split from rapper Jas after two years of dating.
No further details have been revealed.
Christina, 32, had become engaged to Jas in September last year, but kept coy on the romance when quizzed the following month, simply saying: "Maybe I'm engaged. I'm very happy, I'm in a good place."
She hasn't referenced the break-up on social media, but did tweet last night that she'd had a "rough day".
Another post simply said: "Change is good."
Last week, a post to Instagram also hinted at change, saying: "There comes a time in life when you walk away from all the drama and people who create it. Surround yourself with people who make you laugh, forget the bad and focus on the good.
"Love the people who treat you right. Pray for the ones who don't. Life is too short to be anything but happy. Falling down is part of life, getting back up is living."
Back in April, everything had seemed fine between Christina and Jas, with the singer telling People she'd started wedding planning but a date hadn't been set.
"[Jas] is me every day like, 'What are we going to do? What's the date?' And I'm like, 'I don't know! We'll figure it out,'" she said.
Christina was married before, to rapper/producer The-Dream. They have a daughter together, Violet, born in 2010.
