Paris Hilton Taking Hayden Panettiere Under Skanky Wing?

Paris Hilton can do whatever the hell she wants to Doug Reinhardt. Dude has to be well aware of what nastiness he's getting himself into. Literally.

The last time the ho-tel heiress decided to take one of our favorite female stars under her wing, though? We don't have to tell you what happened.

THIS and THAT happened.

So we can't help but be concerned about newly-single Hayden Panettiere, who has apparently been partying with the former sex tape star of late.

Since splitting with 31-year-old Heroes co-star Milo Ventimiglia last month, Hayden, 19, joined Hilton at L.A. hot spots Apple Lounge and Guy’s.

Even worse, she marked her new BFF’s 28th birthday at Paris' pad.

Sounds like the breakup hasn't left her jaded by older men, either.

With Paris as mentor, she’s coming on to every older man in her path, such as Red Hot Chili Peppers’ Anthony Kiedis, 46, and actor Gerard Butler, 39.

“Hayden is really mature, so she goes for guys that are older,” a source tells OK!

That's not what we heard about her at all, but she's only 19, so we sort of understand. It's not like she's parading around clubs in no pants or anything.

Yet. Seriously, we hope she ditches the skank before it's too late. We want our site's gallery of Hayden Panettiere photos to be appropriate for all ages.
