It was a supermodel face-off as Victoria's Secret models Miranda Kerr and Alessandra Ambrosio hit the beach in St Bart's.

While the pair may well work for the same lingerie line, there was no doubt that there was some hot competition between them.

Both showed off their long limbs in a selection of swim suits, including matching white numbers.

Brazilian model Alessandra, 28, was first to show off her figure, after stripping down to a sexy white bikini among an array of other skimpy swimwear numbers.

But it wasn't long before Australian star Miranda, who dates actor Orlando Bloom, followed suit.

She modelled a bright pink bikini, before leaning forward to show off her curves in a sundress.
