Kelly Osbourne is ''hooking up'' with Puff Daddy's stepson Quincy Combs.

The 'Fashion Police' co-host, who split from fiancé Matthew Mosshart in January, has reportedly grown close to Quincy and also has her eye on British model Ricki Hall.

A source told Us Weekly: ''Kelly is single, but she's having a lot of fun. She's been hooking up with Quincy, her really good friend lately...

''It's not serious but he's really hot and he's very into her!''

A few months ago, Quincy, 23, posted a photograph of himself with Kelly, 29, on his Instagram account, with the caption: ''With the oh so eccentric @kellyosbourne!! (sic)''

Quincy is the son of Puff Daddy's on/off girlfriend Kimberly Porter and singer and producer Albert Joseph Brown III, also known as Al B. Sure.

Meanwhile, Kelly is said to be keeping her options open and has been flirting with 27-year-old bearded hunk Ricki.

The insider claims the pair have been messaging via social media and she is fond of the model.

It's no surprise that Kelly isn't short of offers from men after she showed off her enviable figure and pert butt in a thong on Instagram on Friday (20.06.14).

Her hairstylist Ryan Randall is seen sitting next to her in the snap and admiring the view.
