A year and a half after getting engaged to Swiss financier Arpad "Arki" Busson (Elle Macpherson’s ex & baby daddy / mega rich banking guy), Uma Thurman (Ethan Hawke’s ex & baby mamma) and her beau have officially split. So far, there's no official word on the split from the star's reps but there's two theories circulating, one she began to realise she'd be "engaged" to him for EVA just like Elle was...and the second theory is that it was a distance thing, with UMA in New York with her kids and Arki in London. It was of course a "source" close to Uma who let the cat out of the bag. "She has ended her engagement, it happened over two months ago," the "source" said. "They remain friends." But here's a delicious gossipy twist for you to ponder. Back in 2005 Uma made a comedy movie called PRIME. She hooked up with a 23 year old who was infatuated with her character......flash forward to next year, and Uma's off to Paris to begin filming a new movie called BEL AMI with everyone's favourite sparkly boy, Robert Pattinson (23) who will play a young womanising journalist, and Uma will play his much older wife. Can you just imagine the Twi-lunatic meltdown if Uma, who's almost 40, and ready for a little action, decides bust a move on RobPatz!? Would make my year!
