Jeff Goldblum is dating a woman 35 years his junior.

The 56-year-old actor was seen smooching 'Lost' actress Tania Raymonde, 21, during a meal at Los Angeles' Toast Bakery Cafe.

An onlooker said: "Despite the age-gap, Jeff and Tania appeared smitten with one another and couldn't keep their hands to themselves."

Goldblum has previously been married to Patricia Gaul, who he was wed to for six years from 1980 to 1986, and actress Geena Davis.

He co-starred with Davis in three films, including 'Earth Girls Are Easy' and 'The Fly'.

They married in 1987 but divorced in 1990, although remained good friends and Goldblum has since said of his ex-wife: "She's a wonderful person and a wonderful actress."

Raymonde played Alex Rousseau in 'Lost', in which her character was shot and killed, and she also featured in the 2009 season finale of 'Law And Order: Criminal Intent' alongside Goldblum.

In the episode, she played the daughter of a terrorist from the German urban guerilla group the Baader-Meinhof gang.
