After a star-filled start, celebrities are kicking off the second and final weekend of festivities in California’s Coachella Valley. No longer newbies, Kendall and Kylie Jenner returned to the fairgrounds on Friday, hanging out with pal Jaden Smith. At one point, Kendall started dancing with some buddies, and later tried to get Kylie to bust a move. In other interesting moments, Diane Kruger and Joshua Jackson explored the scene, Paris Hilton showed off her latest festival ensemble, and Vanessa Hudgens lit up with a big smile a week after she embraced the celebrity disguise trend.
