Look who's hooking up in Tinseltown

That is just his lightsabre, but he's still happy to see her
So Sienna Miller is giving Penelope Cruz a run for her peso on who can shack up with a co-star the fastest. Miller, still on the rebound and recouping from the fiasco known as Jude Law, has been romantically involved with her Layer Cake co-star Daniel Craig and of course, Law, whom she met on the set of Alfie. Now Canadian actor Hayden Christensen, whom she worked with in the upcoming film Factory Girl, is the object of her affection. Until her next film, that is.

The couple has been spotted canoodling, flirting and (gulp) karaoking at the cast party for Factory Girl. And most recently, they were caught shopping at the mall on a Sunday afternoon – awww, he must really like her like her!

Note: there is only ONE Star Wars reference! Be proud of me!

Life after Jessica for Lachey
Could it be Nick Lachey has found a new main squeeze after his high-profile divorce to pop diva Jessica Simpson? In Touch reports Lachey's been keeping close company with one-time Miss Kentucky USA and would-be actress, Elizabeth Arnold. The pair has been seen "making out" at various L.A. hot spots (note to self: go to L.A.)

Lachey's reps refuse to comment on Nick's busy hands with Arnold but it's safe to say when people see them they will ask, "who's that girl with Nick?" in stead of "There's Jessica and that 98 Degrees guy."

Desperate Booty Calls?
Okay, this one may be a stretch but rumour has it Hollywood's most eligible bachelor George Clooney may be sweeping a Desperate Housewife off her feet. Clooney and Teri Hatcher, who conveniently live on the same street in Studio City (note to self: go to Studio City), have created buzz around Tinseltown that they are dating.

Both, of course have dismissed these rumours, though when asked about it by Extra, Clooney says "Yes, I heard that," before adding, "She's fantastic. She's a friend. I've known her for 15 years."

Translation: "It was bound to happen."
