She's a Belieber! Kourtney Kardashian was at Los Angeles' Staples Center on Sunday, March 20, to catch her former squeeze Justin Bieber's much hyped Purpose world tour with pals Malika Haqq and Big Sean.

The mom of three, 36, who Us Weekly revealed had a fling with Bieber, 22, back in December, posed for a selfie with her friends at the front of the gig, which Malika later shared via Instagram with the caption, "Beliebers."

Earlier in the day, the sexy, single Kardashian set Instagram pulses racing by sharing a revealing snap of herself in a tiny bikini. 

Sunday funday!

"Sunday funday," she captioned the photograph, which displayed her curves in a barely there string bikini.

Kardashian wasn't the only big name who stopped by to lend buddy Bieber some star support. Jennifer Lopez also dropped in, rushing to the venue after attending the Daily Front Row's Fashion Los Angeles event, looking cool in a white T-shirt and fur waistcoat.
