The bikini's back! 90210 star AnnaLynne McCord unzips her wetsuit to reveal her toned body

She might have donned a wetsuit for filming, but we always knew 90210's AnnaLynne McCord couldn't cover up her bikini body for long. The 23-year-old actress was seen on the set of 90210 in Los Angeles - where she has been shooting surfing scenes at the beach - peeling off the multi-coloured wetsuit between takes. And she seemed much more comfortable as she relaxed in the psychedelic print, multi-coloured swimwear

The actress kept her wetsuit on her bottom half, however, opting instead to cover herself with a long coat and swapping her footwear for white flip-flops. And she appeared relaxed as she spent the time between takes hanging out on the beach with co-star Jessica Lowndes

The actress, who plays Naomi on the prime time series, was also seen later with a towel round her head and a plaster on her nose. But it was her character, rather than

AnnaLynne, who sustained the surfing injury - the beach scenes involve Naomi hurting herself after she accepts an invitation from a man to join him in a surfing competition.

The star braved the chilly conditions on set

While the temperature in California yesterday was in the mild low 20s Celsius, fog and clouds meant AnnaLynne had to wear a coat over her usual beach attire.

Over the summer the actress and her sister Angel were dubbed 'the skeletal sisters' after photographs of them on holidays sparked concern over their thin figures. But AnnaLynne has revealed that she wouldn't mind her slender body going up a few sizes if she were to fall pregnant.

The starlet, who is dating Twilight actor Kellan Lutz, says she wants to emulate Brad Pitt and Angelina Jolie's large family when the time is right.

But the actress just had a dressing on her nose as part of a scene in which her character is hurt

'I want like, six (children),' she told Us magazine. 'I would love to adopt and have my own.' For the time being, the actress is concentrating her efforts on work and some worthy causes. She is raising awareness for the St. Bernard Project, which rebuilds homes for Hurricane Katrina victims in New Orleans.

The organisation has so far re-housed 120 families of the thousands still living in trailers and other temporary accommodation.

AnnaLynne says: 'I visited New Orleans for the first time about three years ago... I didn't realise that the devastation would be so great nearly two years after the storm. 'As an American, I was heartbroken. I felt incredibly ignorant to the fact that so much still needed to be done,' she told USA Today.

She has so far made nine trips to Louisiana, and says: 'Every time I visit, they are in a new stage of building, and that's great to see.'
