Jennifer Aniston was snapped going to Leonardo DiCaprio's Hollywood Hills home on Sunday afternoon, along with Selma Blair, Kate Bosworth, Tobey Maguire, Usher and Seth Rogan. What could possibly bring all these celebs together at once? Well, it turns out they were shooting a voting PSA at Leo's place.

The thought of Jen and Leo shacking up never even occurred to us - after all, Leo and Bar are back on, and this was a strictly professional meeting, but after Jen's bodyguard said repeatedly to X17 photographers, "You're not going to start rumors, are you? Don't start any rumors," we're starting to wonder if there is something to report on. If they were just shooting a PSA, why make a fuss about it? Our photogs added that it almost seemed as if "someone" told Jen's bodyguard to talk to the paps about the "story" - just to make it one in the first place!

Jen is single and on the prowl, and if things don't work out with Gerard Butler, we're sure she'll be chasing after other Hollywood hunks, but Leo? And since when did bodyguards act as publicists?!
