St Barts - Beach bum

She's already been putting on very public shows of affection with the husband she's recently reunited with - but Stephanie Seymour appeared to be putting on a quite different performance on her holiday in St Barts yesterday.

The 42-year-old former supermodel's thoughts are clearly never far from her previous day job as she struck a series of bizarre poses on the sand and in the surf in a flesh-coloured bikini.

A Victoria's Secret Angel and ex of Guns N' Roses frontman Axl Rose in days gone past, the beauty put her body into a series of odd-looking shapes more suited to a pop video than a family vacation.

The brunette is enjoying a beach stay in the Caribbean with three of her children - Peter, 17, Harry, 13, and daughter Lily, 6 - together with her art-loving paper tycoon husband of 15 years, Peter Brant, 63.

The couple revealed in September that they were calling off their acrimonious divorce despite already spending millions each on legal fees and had got back together.

They first announced their split in March 2009 and embarked on a bitter battle rife with allegations of infidelity, drug abuse and wild spending sprees and embroiled their children in the process.

Police were called to the couple's home following Seymour's complaint that Brant's security assaulted her, Brant accused the model of drug use and was seeking sole custody of their three children.

However, their relationship seems to be in great shape now - much like Stephanie's beach-ready body.

She's had years of practice, however, having started modelling aged just 14.

She went on to grace more than 300 magazine covers and became one of Sports Illustrated's most celebrated swimsuit models - possibly helping her prowess at the seaside poses above.
