2:56 PM PT -- Kate just responded to the pics, making it clear she's VERY single, saying, "I would like to point out that standing next to someone does not mean I am dating them. Currently in line at the dry cleaners and if that's true I've got a hell of a problem."
Jamie Foxx couldn't keep his hands off Kate Beckinsaleat a fancy party ... and the timing is interesting considering both are recently single.
Jamie and Kate looked pretty comfortable with each other Thursday night at Catch LA, dressed to the nines for a Golden Globe Ambassadors party in West Hollywood. Jamie's got his arm around Kate's lower back, and she's pushing right up against his body.
