Welcome Back, Jonathan Cheban!In case you're wondering what ever happened to publicist not-so-extraordinaire Jonathan Cheban since the glory days of 2005 when he could be seen posing for photographs holding two phones in his hands at once, the answer was revealed on E! last night. (If you don't know who Cheban is and you'd like to get up to speed, see here, here, here and here.) Cheban made an appearance on the acclaimed reality TV show Keeping Up with the Kardashians yesterday, although the Lizzie Grubman protégé was forced to pay the role of confidante to Khloe Kardashian—not Kim—which should give you a good sense for what has happened to his career as a publicist/promoter the past few years.

To be perfectly honest, what Cheban is doing these days wasn't really revealed on the show last night. Sadly, he didn't offer up much detail on his current exploits, although his clothing line, Kritik, does still appear to be business, provided you're willing to take the existence of a MySpace page as proof. (The same can't be said for his Clarendon t-shirt line, alas.) And he is pretty active on Twitter, which as we all know, represents a full-time job for loads of people in celebrity/social circles. Whatever it is he's doing, it appears to be working out nicely. On the Kardashian show last night (clip here), Cheban can be seen cruising around town in "his" chauffeur-driven black SUV.
