David Hasselhoff is headed back to school - he's to star as a pupil in his girlfriend's new music video.

The former Baywatch hunk is helping his model girlfriend Anouska de Georgiou launch a pop career by starring in a promo for her upcoming single.

And the socialite is ensuring the promo clip will be suitably embarrassing for her beau - by dressing him up in a silly costume.

She explains, "It's a school theme and he'll be a schoolboy."
