The 27-year-old ‘Candy’ singer and the 38-year-old former ‘Friends’ star were dining at the exclusive Amici Trattoria Italian restaurant in Beverly Hills when they started kissing and cuddling.
A fellow diner told the New York Daily News newspaper: “He was already seated and waited for her for 15 minutes until she arrived. He stood up to greet her and gave her a kiss on the cheek. They were holding hands across the table and being really close and laughing a lot the whole time.”
Another source said: “After they finished their food she went to sit next to him and they started cuddling and nuzzling into one another. They looked really into each other.”
Matthew, who has previously dated Elizabeth Hurley, Heather Graham and Julia Roberts, was most recently romantically linked to Meg Ryan.
Mandy has been single since splitting with ‘Scrubs’ star Zach Braff last year.
