ROBERT PATTINSON and KRISTEN STEWART showed up together at the Coachella music festival in Indio, California over the weekend, along with KATY PERRY.
There could have been an embarrassing run-in, because LIBERTY ROSS was there, too. She's the estranged wife of Kristen's"Snow White" director, and as you probably know, Kristen is the reason they're estranged.
(Liberty is reportedly hooking up with music exec Jimmy Iovine now. She was hanging out with him and BONO over the weekend.)
Meanwhile, LINDSAY LOHAN showed up with her BROTHER. Sources say she was telling friends she planned to remain SOBER all weekend. (Check out pictures of Rob, Kristen, Katy, Liberty, Bono and Lindsay here.) (TooFab, Us Weekly,TMZ)
