I hear K.Stew arrived in the desert on Friday but managed to keep a low profile until Sunday, when she stopped by the Lacoste House for a quick photo op.
Rob Pattinson couldn't make it to the fest due to his filming schedule. But even though he supposedly attended last year, it doesn't look like he gave her any wardrobe pointers since she was clad in all black despite the sweltering temp.
So who traveled with the actress instead?
"She was with her brother and a few friends," a source tells me. "She stayed about 30 minutes in between catching shows."
Kristen scored some new Lacoste aviator shades at the pool party before heading back into the crowded festival.
