Justin Bieber performs for a star-studded crowd in L.A. — and manages not to get sick again!

Even Hollywood is obsessed with Justin Bieber! The 18-year-old performed the second of two sold-out concerts at L.A.'s Staples Center on Wednesday, where the crowd included Heidi Klum, Kylie and Kendall Jenner, and Katy Perry. The "Wide Awake" singer tweeted that she had been there to witness the wonder of the Biebs.

Klum was accompanied by two of her children, 8-year-old Leni and 5-year-old Johan, and her bodyguard-turned-boyfriend Martin Kristen. By the end of the night, the supermodel spawn had pulled Justin Bieber T-shirts on over their clothes and were clearly tuckered out!

Khloe Kardashian chaperoned little sisters 16-year-old Kendall and 15-year-old Kylie Jenner for the evening, and Kylie enjoyed the concert so much that she checked it out on both nights! That could be because Kylie's friend Cody Simpson, as well as "Call Me Maybe" singer Carly Rae Jepsen, opened the show for the Biebs.

Fortunately for Bieber, he made it through the gig without throwing up onstage as he did Saturday during the kickoff of his world tour in Glendale, Arizona. The teen later attributed the onstage illness to washing down spaghetti Bolognese with whole milk before beginning his set. He did have another problem, though. During his Tuesday show, his $100,000 Fisker Karma vehicle — yes, that one again — was towed! TMZ reports that someone on his staff left it at the Shore Hotel in Santa Monica in a 15-minute parking spot for hours. Whoops!
