WWW- TV and film star Sarah Michelle Gellar has finally decided to bare all in a sexy ad campaign for the classic moisturiser, Vaseline.

In these tasteful images the Buffy the Vampire Slayer actress stripped off to reveal her flawless, sun-kissed skin, but she didn’t let anyone take a peek at her face.

Gellar, 30, has always vowed that she would never reveal all for any film role and like many Hollywood actresses has reportedly had no nudity clauses written into film contracts.

Vaseline challenged their customers to guess the identity of the mystery celebrity in their new campaign.

In one close up picture only her well manicured hand can be seen resting on her arm.

In another her hair falls over her face as she wraps her arms around her bare legs.

The skin care company then gives a glimpse of the star’s lips and chin with the slogan “Keeping skin amazing”.

It is thought that this could most revealing photoshoot the actress.

Gellar went some way to losing her clean-cut image when she starred in the 1999 film Cruel Intentions.

The actress was at the centre of much publicity when her character shared a steamy lesbian kiss with co-star Selma Blair.

Gellar met her husband Freddie Prinze, Jr., during filming of the 1997 teen horror film I Know What You Did Last Summer.

The glamourous star was recently voted one of Hello! magazine’s most elegant women.

Gellar’s latest film role sees her play Alice in Wonderland as a young woman in a movie based on the computer game American McGee’s Alice.

The film will be released in summer 2008.
