Russell Brand has been having a ''passionate fling'' with model-and-MTV presenter Kate Peck.

The British comedian was recently in Australia for his 'I Am A Walrus' stand-up tour and met the 25-year-old blonde beauty at the ARIA Music Awards in Sydney last month where they both hit it off and arranged to meet several times at the ''swanky'' Park Hyatt Hotel.

A source told The Sun newspaper: ''They've been enjoying quite a passionate fling, mostly at the swanky Park Hyatt. They've seen each other a few times, Kate likes his cheekiness, he's definitely her type.

''Unlike former girlfriends, Russell wanted to keep it all top secret.''

Although Russell, 37, has left Down Under he and Kate - who describes herself as ''MTV's newest VJ! lunatic, model and motorcycle maniac'' on her Twitter page - are ''still in contact''.

Kate is one of many women Russell has been linked to since his split from wife Katy Perry last December, with conquests including Spice Girls star Geri Halliwell, 40, and 27-year-old Isabella Brewster - whose sister is 'The Fast and The Furious' actress Jordana Brewster.

One former lover of Russell, Becki Seddiki, revealed the funnyman has high expectations for his flings, especially in the bedroom.

She said: ''He is a man who needs a lot of sex and the one thing all his women must be is wild ion bed.''
