Natalie Portman laughed between takes while filming an Ivan Reitman-produced comedy in LA with her costar Ashton Kutcher yesterday. Ashton's favorite mode of communication, Twitter, which helped land him on Time Magazine's 100 Most Influential People list, hit a snag yesterday when everyone's stats dropped to zero. His 4.8 million follower number has since returned, which means he's back to spreading his many philanthropic messages through his feed. Natalie does her part for charity as well, and her latest good deed, supporting the NYC ballet, had the added bonus of helping her dancer boyfriend, Benjamin Millepied.
