A BASILDON babe is vamping it up to advertise a new British comedy film.

Glamour model Porchia Watson, 21, has been picked to be the billboard star of the Brit flick Lesbian Vampire Killers.

The film, a tongue-in-cheek tribute to the Hammer Horror films of the past, stars Gavin and Stacey’s James Corden and Matthew Horne, who put Billericay on the map with the BBC sitcom, which is partly set in the town.

In the film the actors’ characters take a lads’ holiday in Wales and discover the local women are blood-sucking lesbians.

Porchia, who has modelled for national newspapers and magazines, appears as a bare-chested vampire in the poster, though only the most ardent fans of her asssets are likely to recognise her – only the lower half of her face is shown.

She said: “The shoot was great fun. It let me get in touch with my dark side.”

The film opens in cinemas on March 20.
