Sources spotted the pair last week all over each other in the L.A. hotel Chateau Marmont.
"Kate and Orlando are definitely more than just good friends now ... They were kissing and cuddling in the corner of the lobby bar and didn't seem to care who saw them. They even stayed past closing time because they were enjoying each other's company," said this totally reliable anonymous person.
Bloom, of course, had been rumored to have swung with Penelope Cruz for awhile, but that talk has died down.
If this story is true, though, The Hollywood Gossip would like to throw our support behind Dunst and Bloom (aka Doom?). It's nice to see some people getting together just as others - such as Nicole Richie and Rachel Zoe - are breaking up.
