Christian Slater has been seen kissing Jimmy Choo founder Tamara Mellon.
The 38-year-old actor - who is in London preparing for his upcoming role in the West End play Swimming with Sharks - took Tamara to watch Robin Thicke in concert at Camden's Koko music venue, followed by an intimate dinner at Mayfair's exclusive Japanese restaurant Sumosan, where they were seen canoodling.
An onlooker told the Daily Mirror: "They were kissing, and sitting very close together. They looked absolutely smitten!"
Christian and Tamara - who launched the designer shoe company favoured by celebrities including Sarah Jessica Parker - first sparked romance rumours after being seen talking intensely at last week's VandA Golden Age of Couture Gala in London.
The pair spent most of the evening in each other's company chatting and laughing.
The True Romance star has been romantically linked to a series of Hollywood beauties in the past, including Winona Ryder, Christina Applegate and Sharon Stone.
Tamara, 40, married wealthy heir Matthew Mellon II in 2000 but the pair divorced in 2005.
Tamara and Matthew have one daughter together, Araminta.
