Quentin Tarantino is reportedly dating Uma Thurman.

The Pulp Fiction director, 51, has "loved" the newly-single actress - whom he previously called his "muse" - for years and they are said to have taken their relationship to the next level after traveling to the Cannes International Film Festival together to attend the closing ceremony last Sunday.

"They had a thing and got together again recently. He's loved her for years," a source said.

The duo - who also collaborated on the Kill Bill films together - walked the red carpet arm-in-arm before presenting Winter Sleep director Nuri Bilge Ceylan with the prestigious Palme d'Or at the end of the star-studded film festival.

"There has always been an attraction. She has indulged from time to time, and that's how their relationship has always worked," another insider said.

Uma, 43, recently ended her engagement with French billionaire Arpad Busson for the second time, with whom she has 21-month-old daughter Luna. The blonde beauty, who also has daughter Mia, 15, and son Levon, 12, with ex-husband Ethan Hawke, previously admitted that she is happier than she has been in years: "I'm happier now than I've been in many, many years. I'm trying to live as peaceful a personal life as possible. I guess I'm less jaded now than I've ever been, definitely less than when I was younger."
