Movie stars and musicians alike flocked to Indio, Calif., for the Coachella Valley Music and Arts Festival, making the list of celebrity sightings long and varied.

Among the unexpected is Clint Eastwood, who checked out the festival with his daughter Francesca. The 82-year-old actor took his western gunslinger experience and put it to use at the water gun race, reports omg!.

While Twilight fans were elated to see Robert Pattinson and Kristen Stewart's hand holding during the weekend's events, they weren't the only star couples to turn out. Inglourious Basterd's Diane Kruger and Fringe's Joshua Jackson were also spotted hand in hand.

Meanwhile, on the musical side of things, Brit R&B singer Rita Ora made an appearance with a mysterious male companion, although her fashion sense took some bashing. Katy Perry, however, was deemed to be one of the best dressed by Perez Hilton as she rotated through a number of outfits.

Lindsay Lohan even managed to make an appearance, along with her brother Cody and sister Ali, despite her impending rehab stint.

Although the first weekend of the festival has come to an end, celebs may be back for more from April 19-22.
