Last week Sophie Monk filmed a spot for an Australian TV show while on a beach in Maui. The toned Australian model wore a black string bikini and performed a few yoga stretches before sipping a Pepsi.

Monk has been in Hawaii for the past few weeks working on the show.

Britney Spears and her boyfriend Jason Trawick have also been relaxing in Hawaii. The pop star wore a turquoise bikini and was also spotted with a drink in hand.
