P. Diddy's kids think Justin Bieber is "cool".

The hip-hop star has five children with various partners, including twin girls D'Lila and Jessie and daughter Chance, who are all around six.

His latest Instagram picture shows three girls posing with teen sensation Justin.

The children are huddled together, grinning, as the 19-year-old stands behind them, posing with a headset.

"After the girls took this picture, they called me and told me that the only person as cool as me is this guy! Thank you @justinbieber ! (sic)," Diddy captioned the snap.

Justin promptly retweeted the musician's message on his own Twitter account.

While Diddy and his family are clearly big fans of Justin's, not everyone has been so enamoured with the star recently.

The teenage heartthrob has come under fire for a variety of reasons, including smoking what appeared to be marijuana, speeding around in his Ferrari and reportedly assaulting a neighbour.

Despite the negativity, Justin has been focusing on his amazing career.

"Alot of things have been said but I do this for you! #mybeliebers," he tweeted.

"I love what I do and I'm #blessed to do it (sic)."

Justin hasn't released an album since last year's Believe, but has been working on music with British boyband The Wanted.

He's also been teasing new tracks on his Twitter account.

"have alot of new music coming. #creativity (sic)" he promised.
