Chris Brown launched a Twitter rant apparently aimed at R&B singer Kehlani Parrish following her suicide attempt.

The Did I star, 20, hit rock bottom after she was attacked on social media following reports suggesting she had cheated on basketball player Kyrie Irving with her ex.

She took to Instagram in the early hours of Tuesday (29Mar16) and shared a photo of herself in a hospital bed, with an intravenous tube in her arm.

"today I wanted to leave this earth," she captioned the now-deleted image. "Being completely selfish for once. Never thought I'd get to such a low point. But.. Don't believe the blogs you read .. No one was cheated on and I'm not a bad person... Everyone is hurt and everyone is in a place of misunderstanding...

"But as of today, I had no single wish to see tomorrow... But God saved me for a reason, and for that... I must be grateful... Cuz (sic) I'm not in heaven right now for a reason..."

Following her emotional revelation, several stars including Nick Cannon came out in support of Kehlani, praising her for her bravery in coming forward and revealing her battle.

However, Chris appeared to have taken offence to Kehlani's admission, writing a string of posts on his Twitter page on Tuesday night that appeared to reference the singer's suicide attempt.

"There is no attempting suicide," he wrote. "Stop flexing for the gram. Doing s**t for sympathy so them comments under your pics don't look so bad (sic)."

After admitting her attempt to take her own life, Kehlani then tried to clear up the unfounded claims about her love life, revealing she and Cleveland Cavaliers ace Kyrie, who she became linked to late last year (15), recently parted ways, and she has since reunited with former lover PartyNextDoor.

Kehlani went on to praise the Drake affiliate, real name Jahron Anthony Brathwaite, for remaining by her side in hospital after reportedly saving her life.

Chris had kicked things off by apparently deciding to offer his own relationship advice, writing: "Girls be mad at a n***a for f**king around wit b***hes but her DMs got more names then the Declaration of Independence. #YEAHIMTHROWINGSHADE (sic)."

While he never referred to Kehlani by name, he did write: "#KYRIEMVP", a clear reference to Irving alongside the acronym meaning Most Valuable Player.

He concluded: "OK IM DONE. Guess she gone have to watch the games from a real 'box' now. 'THE TELEVISION' #OHB 'OUTTA HERE BIH' (out of here b***h) (sic)."

Chris' Twitter rant drew criticism from many people on Twitter with one writing: "I can’t believe I use to look up to you."

Another added: "Relationship advice from Chris Brown .. 2016 is wild."
