Leonardo DiCaprio

Sienna Miller has said in the past that humans are basically a bunch of f*%king animals who can't be counted on to be monogamous.

But despite a rough breakup from Jude Law, the actress denies she's looking for some rebound action with Leonardo DiCaprio, who she's been linked to of late.

"Absolutely no truth, I'm afraid to say," Sienna Miller told E! before the much-anticipated Golden Globe Awards in Los Angeles.

The 25-year-old, who's been popularizing the all-vodka diet, was responding to a question about a story that she had been seen with DiCaprio "in an impossibly romantic way."

The Pittsburgh hater (and native) said she and DiCaprio were "buddies from a while ago" but she hadn't seen him for more than a year.

British tabloids reported last year that the two were seen acting cosily at a L.A. nightclub, but both stars have denied that a nude Sienna Miller has made an appearance. Sad.

Miller, who recently finished making the film Factory Girl, has had an on-and-off relationship with Jude Law, and hopes that she may one day rekindle her romance with him.

DiCaprio, who in addition to looking a lot like Grey's Anatomy star Eric Dane, picked up not one but two Golden Globe nominations for his roles in Blood Diamond and The Departed. 

Nominees for the Golden Globes were announced this morning and two actors stood out from the rest:

1. Leonardo DiCaprio, who scored best actor in a drama nods for both Blood Diamond and The Departed.
2. Jennifer Hudson, nominated for best supporting actress in her big-screen debut, Dreamgirls.

"I'm overwhelmed right now," Hudson said on the Today show. "I just started screaming when they said the names."

Dreamgirls racked up multiple nominations, including a best actress, musical or comedy, nod for star Beyoncé Knowles and a supporting actor nomination for Eddie Murphy.

Actress nominees for movie dramas are: Penelope Cruz, for Volver; Judi Dench, Notes on a Scandal; Maggie Gyllenhaal, Sherrybaby; Helen Mirren, The Queen; and Kate Winslet, Little Children.

Comedy/musical actress nominees are: Annette Bening, Running With Scissors; Toni Collette, Little Miss Sunshine; Beyonce, Dreamgirls; Meryl Streep, The Devil Wears Prada; and Rene Zellweger, Miss Potter.

Besides Murphy, other supporting actor nominees include: Jack Nicholson and Mark Wahlberg (in The Departed) and Brad Pitt (Babel).

Really, Leo? You're a famous actor, largely well-known for taking on daring roles and challenges.

Therefore, we expect more from your Halloween costume selection.

Just look at Mary-Kate Olsen, for example. She was outrageous enough to go as a ghost.

Then there are these creepy ideas frm actresses such as Kate Bosworth and Nicole Richie. We shiver just looking at them.

So just because The Departed was one of the best movies we've seen this year doesn't mean you can skate by with a lame gorilla outfit, Leonardo DiCaprio. Use some imagination, ok?

Like Pete Doherty. He's gonna go as a sober fiance. We can't wait to see that one!

We're reaching a bit on this one. We admit it up front. But then again, all our Celebrity Look-Alikes and going to seem like dead-ringers compared to a pair of lovely ladies whose only real common trait is DSL (and by that we mean their preferred Internet connection, of course), or a popular actor and a one-time Iraqi strongman.

Anyway, here's the latest pair of celebs we thought warranted a look-like mention. On the left, we have Leonardo DiCaprio, 31, star of Martin Scorcese's new movie The Departed. On the right, fellow actor Eric Dane, 34, a.k.a. "McSteamy" on Grey's Anatomy. Maybe you don't see it, but we think there's a resemblance between these Hollywood hunks.
