London: Former 'Friends' actor Matt LeBlanc is reportedly "besotted" with his new gilfriend Aurora Mulligan, who works as an assistant producer on the TV show 'Top Gear', which he co-hosts.

The pair went public with their romance last weekend as they enjoyed a date at a horse racing event in West Sussex, South England, and fellow race-goers say they couldn't keep their hands off each other, reports femalefirst.co.uk.

An onlooker told The Sun newspaper: "Matt and Aurora were inseparable throughout the whole day. They were very tactile and Matt seemed to be very taken by Aurora as he laughed chatted intimately with her. Aurora just kept laughing at all his jokes and is clearly besotted with the American superstar.

"You wouldn't have known that they were work colleagues at all. It is definitely more than just a professional relationship."

LeBlanc and Mulligan were first linked with each other earlier this year, but his spokesman insisted it was a "strictly a work relationship".

However, a "Top Gear" source has reportedly confirmed that the friendship between the two has blossomed into something more serious.

"This has become a romance. Matt spends more time with Aurora than anyone else in the crew and there's definitely a blossoming relationship there," added the insider.

LeBlanc was previously married to model Melissa McKnight and they have a 12-year-old daughter, Marina, together.
