Brad Pitt is still single following his split from Angelina Jolie, a source close to the actor tells ET.
Despite recent tabloid reports that Pitt was cozying up to Sienna Miller at the Glastonbury music festival in the U.K. over the weekend, and that he was also spotted getting flirty with supermodel Elle Macpherson -- who recently split from billionaire Jeffrey Soffer -- in Los Angeles, our source says the 53-year-old actor isn't dating anyone. The source adds that Pitt is actually friends with a male pal of Miller, and that there have been no romantic displays between him and the British actress.
On Friday, Pitt was spotted hanging out with Bradley Cooper and Tilda Swinton at the Glastonbury Festival.
Interestingly enough, ET spoke to 35-year-old Miller in April about Pitt, when he made a surprise appearance at The Lost City of Z premiere in Los Angeles.
"He's involved in the film in that he found the book and developed it and hired James [Gray, the director]. And I think as a producer was very active," Miller, who stars in the film, shared.
"He's obviously a very handsome producer," she added.
