Kourtney Kardashian looks like she still has Bieber fever!

The mom of three took a break from snapping selfies at home to attend Justin Bieber's Purpose tour show with some friends at the Staples Center on Sunday night. After their summer fling, we weren't sure if they were still on good terms -- but it looks like Kourt couldn't get enough. And we can't blame her -- we'd love to take a bite out of the Biebs!

Her bestie Malika Haqq posted a snap from the star-studded concert -- and it looks like the pals were having a blast during the show.

After the show, the oldest Kardashian, who wore some super sexy thigh high boots, made a stop at her brother's favorite spot, In 'n' Out, to grab some late-night grub. We guess she didn't make a night of it with her former fling!

Despite not having another romp with the Canadian cutie, Kourtney seems like she'll take what she can get in the validation department. The reality star posted a provocative bikini photo earlier in the day on Sunday.
