Orlando Bloom is dating a Jenner?

Orlando Bloom, I worry about you sometimes. You generally seem like a pretty cool guy, as famous people go, be willing to poke fun at yourself on “Extras,” for example, or just generally being dapper and laid back. Then every once in a while you end up in some situation that makes me question your judgment. Like a slap-fight in Ibiza with Justin Bieber, for instance.

Or this: Bloom is reportedly dating junior varsity Kardashian and model Kendall Jenner — but, like, secretly — since first cozying up to her at a private film screening in L.A. over the summer, according to the Sun.

“The age difference doesn’t seem to bother them, although it’s far too early for either to tell if it’s going to develop into something serious,” a source says. What age difference, you might ask? Oh, just 19 years or so — or exactly as old as Jenner is. I mean, it’s not as bad as Mel Gibson and his new 24-year-old girlfriend, but still.
