California girl Kristin Cavallari puts her beach body on show in a colourful bikini

Reality TV star Kristin Cavallari has been spending most of her time in Chicago with her new love, but she's still a California girl at heart.

The former Hills beauty flashed some skin on the weekend as she strolled down the beach in Santa Monica, California.

The 24-year-old reality star debuted her enviable figure in a skimpy bright multi-coloured two piece as the temperatures began to rise in Los Angeles.

Kristin was back in Los Angeles just for the weekend before jetting back to Chicago.

The reality star, who is dating Chicago Bears quarterback Jay Cutler, has spent an increasing amount of time in the windy city to be close to her beau.

The couple met in August last year and became inseparable almost instantly.
Back in January, while celebrating her birthday, Kristin revealed that the pair are very much in love.

'I'm just enjoying my personal life and taking a little time away from the public eye, which is why Chicago is great for me,' she told People Magazine at the time.

'My mum and that whole side of the family is there. And Jay is there. It's nice to be able to hang out with my mom, and, you know, I'm in love and it's been great.'
