Pictures of Natalie Portman and Ashton Kutcher Kissing on the Set of Their New Movie

Ashton Smooches Natalie but Isn't Kissing Up to Miley's Critics

Ashton Kutcher and Natalie Portman were spotted locking lips on the set of their untitled Ivan Reitman romantic comedy yesterday in LA. The pair was cracking up with the crew earlier this week but this time it was all about catching the PDA on film. Influential media mogul Ashton took to Twitter this week to chime in defending Miley Cyrus against critics harshly criticizing her risqué dance moves. Later this month he'll have to switch gears from shooting with Natalie to promoting with Katherine Heigl leading up to the June 4 release of Killers.
