The 54 year old, who is best known as playing Joey Tribbiani in the US sitcom, has reportedly parted from the 36 year old TV producer after the pair were first linked in 2016 when Matt joined the BBC motoring series.
Matt, who was pictured looking downcast at a car body shop in the Los Angeles neighbourhood of Sherman Oaks at the weekend, is said to have ‘taken the news particularly hard’.
The US actor donned a black t-shirt printed with ‘genuine Ford parts’ along with a baseball cap and shades as he walked with his head down through the car park.

“It’s a huge shame and Matt has taken the news particularly hard, as anyone would,” a source told The Sun.
They continued: “He and Aurora fell for each on Top Gear and although there was a pretty big age gap they were a really great match.”
The source claimed that ‘it was hard’ for the couple with Matt, who left Top Gear in 2016, is ‘mainly based out in LA’ while Aurora, who hails from Co. Fermanagh, Northern Ireland, was working in the UK.
OK! has contacted a representative of Matt LeBlanc for comment.
Matt and Aurora met on the set of Top Gear and the Norther Irish producer even had a cameo on the show.
Aurora was born in Northern Ireland and she went on to study politics, political science and government at Liverpool University before she embarked on a career in television working for the likes of ITV, Channel 5 and the BBC.
Aurora and Matt were connected after being spotted out and about together several times.
Back in 2016, an insider told The Sun: “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’s definitely more than just a professional relationship.”
The pair are apply together and Matt nicknames his girlfriend “honey,” and wrote in 2017: “I’m gonna be on tonight and my honey came to support me. How nice. #manwithaplan #cbs @auroramulligan@latelateshow.”
Aurora has a private Instagram account on which she has 3,400 followers and Matt hasn’t shared any snaps with his partner on his social media.
Prior to Aurora, Matt has had several high-profile relationships and married Melissa McKnight in 2003 with the couple welcoming a daughter named Marina Pearl in 2005.
Matt and Melissa split after he was caught getting too close to a stripper on a night out, and the actor said he hardly left the house for years afterwards, calling it a “very dark time.”
The star also dated Playboy cover model Teri Copley between 1989 and 1990 and he was rumoured to be dating Kate Hudson in 1996.
The star had a very long relationship with Andrea Anders, who he dated from 2006 until January 2015.
