Is there anything the Olsen Twins - or as PETA calls them, the trashy, fur-wearing Trollsen Twins - love more these days than making out with random dudes?

Well, E! Online reports that Mary-Kate Olsen is the latest of the brittle twins to be spotted in a club with her tongue lodged firmly in the throat of a beautiful man.

The lucky fellow? Dave Annable, of Brothers & Sisters fame. Holla!

Dave Annable, who does a terrific job as the youngest of said siblings, Justin, on the acclaimed series, is quite a hunk. We can see what Mary-Kate Olsen sees in him.

Another plus is that he’s only seven years older than Mary-Kate Olsen, which is much more respectable than her sister’s alleged Lance Armstrong hookup.

Nevertheless, we don’t expect Dave Annable to last - Mary-Kate boy toys never do. We’d love to place bets on which famous stud one of our favorite, frail twins will make out with next, but we just can’t. Oh whatever, we’ll give it a shot. Some odds:

• Sean Avery - 3:2
• Hunter Parrish - 4:1
• Stavros Niarchos - 9:2
• Cisco Adler - 6:1
• Max Snow (whatever happened to that guy) - 20:1
• Perez Hilton - 2,000:1

Mary-Kate Olsen and Paris Hilton’s on-off boytoy, Stavros Niarchos are back together, and making out in puiblic and all that fun stuff. I get the two confused… is it Ashley Olsen or Mary-Kate that likes men old enough to be their father? I can’t keep them straight, so most likely, both. From Life & Style:

“”They were super into each other,” clubgoer Susan McGinley tells Life & Style. Adds a second partyer [sic], Stacey Kives, “He was making moves and she was eating it up.”

The duo kissed passionately for a few minutes, says the first witness - and then Mary-Kate, 21, put her hand over her mouth and giggled.

One person wasn’t laughing. When Stavros’ on-again, off-again love Paris Hilton, 26, heard about the PDA, she was infuriated. “She thinks MK was publicly hooking up with Stavros just to piss her off,” says an insider close to Paris.

In fact, the insider says, Paris believes the hookup was all about revenge. Back in 2005, MK was in what she thought was a serious relationship with Stavros, 22, when the shipping heir started seeing Paris as well. “Mary-Kate has hated Paris ever since,” notes a mutual friend… Making matters worse, Nicky Hilton is now dating David Katzenberg, another one of Mary-Kate’s exes!”

Paris Hilton may not be the nicest girl in the world, but at least she’s not a total fashion retard. Jesus Christ, what is Mary-Kate wearing? And is it just me, or is that tan looking severely unhealthy? On the other hand, maybe the fugly heels she has on are cutting off the circulation to her feet. Seriously, Paris, don’t sweat Mary-Kate stealing your ex; you can do way better. Stavros looks like a pirate with a lazy eye in this picture. (Just for FeFe.)
