Robert Pattinson

Robert Pattinson and Liberty Ross narrowly escaped an "extremely awkward" encounter on Saturday (12.04.14).

The 'Twilight Saga' hunk and the British model, who were both left devastated when their partners, Kristen Stewart and Rupert Sanders, enjoyed a passionate affair in July 2012, were reportedly barely able to avoid one another at the second annual H&M Loves Music party at the Coachella music festival in Indio, California.

A source told E! News that the heartthrob, 27, and the 35-year-old brunette beauty, who filed for divorce from Rupert in January 2013, "didn't speak to each other, but both definitely saw each other."

The eyewitness said that the entire experience was "extremely awkward" for both Robert and Liberty, who has two children, son Tennyson and daughter Skyla, with Rupert.

But the source added: "He was cool, she was cool and they just kept moving along."

Robert attended the bash with a group of friends, including Katy Perry and fashion designer Alexander Wang.

The 'Water for Elephants' star ended his on-again, off-again romance with Kristen, 24, for good last summer, after reportedly discovering she was back in contact with her 'Snow White and the Huntsman' director Rupert.

Liberty, who began dating Interscope Records co-founder Jimmy Iovine in February 2013, previously admitted that the public breakdown of her 16-year relationship with Rupert was "horrible" but insisted that she was over him.

She said: "I have no words to describe what we went through. But I think, for me, something always has to completely die for there to be a rebirth. And I feel like I'm going through a rebirth."
