Kelly Osbourne's family love her boyfriend Matthew Mosshart.

The 'Fashion Police' star has been dating the 29-year-old vegan chef for over a year and her parents Sharon and Ozzy are huge fans.

A source said: ''Kelly's family love her boyfriend.

''They think he's the nicest guy she's ever dated. He is very patient and down to earth.''

Friends also believe laid back Matthew is perfect for 28-year-old Kelly because he keeps her grounded.

The insider added to Us Weekly magazine: ''She tends to be kind of a diva, so his sweet nature is good for her.

''Kelly is the happiest she's ever been. Her career is going well and she's in a healthy relationship with a wonderful guy.''

Kelly recently proclaimed Matthew to be the ''love of her life''.

She wrote on twitter: ''Just had the best #MosshartFamily dinner! having a chef that is not only your boyfriend but the love of my life is next level! (sic)''

Kelly - who previously dated model Luke Worrall before he cheated on her with a transsexual - often enjoys foodie days with her boyfriend, and is especially impressed with his breakfast skills.

Earlier this year she wrote on twitter: ''Just got back from the most amazing/romantic anniversary weekend getaway with my honey!

''We ate fresh made crepes with Nutella every morning in bed it was #heaven! (sic)''
