During the actress's trip to Europe earlier this month to promote her new film Marley & Me, she was apparently infuriated when the musician claimed he was too busy to return her calls, but found time to update his Twitter page. A friend of the 40-year-old actress said she was unimpressed he found time to write random ramblings on the site, but not to contact her.

A pal claimed in America's Star magazine: "John suddenly stopped calling her or returning her e-mails and when she would finally catch up with him, he'd say, 'I've been so busy with work. I'm sorry I haven't had time to call you back.' Jen was fuming. There he was, telling her he didn't have time for her and yet his page was filled with Twitter updates. Every few hours, sometimes minutes, he'd update with some stupid line. And in her mind, she was like, 'He has time for all this Twittering but he can't send me a text, an email, make a call?'"
