Televisionista: LOST Spoilers: Bai Ling Hits The Sheets With Matthew Fox In Latest LOST Moment

Fans of Matthew Fox's LOST character Jack have been asking for months - how did the sexy doctor really get his tattoos? We are about to find out in a steamy flashback set in Thailand.

The latest LOST moment streamed yesterday on ABC's official website revealed an upcoming erotic scene featuring a beautiful China-born actress Bai Ling.

Recently, the actress revealed she plays a woman named Achara who seduces Jack. They become lovers and they spend time together, but he never really gets to know her as she never lets him.

Finally, there is a psychological twist and an unhappy ending including betrayal.

Two days before the fall finale aired in early November, the LOST cast and crew filmed the scene pictured below in which the doctor gets beaten up by a bunch of thugs which may give you some idea of how things are going to work out for Jack.

Turns out the doctor had even more baggage before the crash than we had thought.

Bai Ling revealed she was cast to appear in three episodes of LOST this season.

This is somewhat confusing as even principal characters such as Jack do not get more than 3 flashbacks per season and Jack has already had one in the season premiere episode in October. Would Achara appear on the island as well?

Entertainment Weekly contradicted the actress, saying she would only appear in a single episode.
