Celebrity worlds collided (in a good way) on Wednesday night, as some famous faces popped up in the crowd as Rihanna rocked Anaheim, California — namely, Khloe Kardashian.

Khloe was out to have a good time for Riri’s LOUD tour as it made its stop at the Honda Center in Anaheim. With assistant Malika and brother Rob in tow, Khloe was all smiles as she made her way into the arena for the gig. She was even spotted with her Flipcam at the ready, taking in all of the action. Can’t wait to see if she posts any video on her blog!

The concert was apparently a hit, as Khloe said on Twitter: “Had so much fun at the #LoudTour! Amazing performance by @rihanna you won’t want to miss that sexy kitty! #RihannasNavy was in full effect.”

One night earlier, Rihanna brought her tunes and sexy wardrobe to Los Angeles.
