The pair will be attending the premiere of the relationship-book-inspired ensemble comedy 'He''s Just Not That Into You', separately. The two had started seeing one another in August 2007 after they met on the set of the film, which will be out in theatres on Feb 6, 2009, and which also stars Jennifer Aniston, Ben Affleck and Scarlett Johansson.
Barrymore had been very ecstatic about the relationship and in March she had told Vogue that she was so happy, "my cheeks hurt. They''re two peas in a pod, they''re made for each other," E!online had quoted Barrymore''s Charlie''s Angels co-star Sam Rockwell as telling People just last month. "They''re like Mr. and Mrs. Warmth," he had added.
