Kourtney Kardashian stepped out with son Mason on Tuesday, and is it just us, or is the 37-year-old reality starlet trying to fly under the radar? After rumors that she's romancing model Jourdan Dunn's ex boyfriend Younes Bendjima, 23, we can't help but wonder!

Bendjima split from Dunn about a week ago, and according to The Sun, Kourt first met the model/former boxer at Paris Fashion Week. And get this -- the two were hanging out on October 3, at the same time Kim Kardashian was robbed at gunpoint in her apartment.

Bendjima "has quietly sparked a relationship with Kourtney and really fancies her," a source told The Daily Mail. "They aren’t ready to go public, [but[ there’s a real chemistry between them." First Bieber and now this dude? Seems like Kourt DEF has a thing for younger men.
