Scott Disick actually did her a favor by cheating on her!

Kourtney Kardashian hit the gym when she split from her baby daddy last summer, and the results are visible! She clearly loves her slimmed down physique, because she shared this "belfie" of herself sunbathing in a leopard print bikini over the weekend. The mother-of-three has never looked better!

Maybe this is why Justin Bieber is hot for the cougar!

According to reports, The Biebs and Kourtney continue to enjoy secret make out sessions and hook ups, most recently at the after party of his concert in LA. "When Kourtney was ready to leave with her sister and Kanye, she and Justin shared a long embrace — he said he didn’t want her to go. He started to kiss her neck and then a handler held up his jacket to cover them as they started making out. Justin was biting her lip," a source dished to Hollywood Life.

Good thing she has a hot body, because her personality is wretched!
