Jen dumped John over Twitter use - report
Jennifer Aniston reportedly dumped John Mayer because he was spending too much time on social networking site Twitter.
The Marley and Me star reportedly grew increasingly irritated with the amount of time John spent posting Twitter updates after telling her he was "too busy" to see her.
A source revealed: "John suddenly stopped calling her or returning her emails 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 email you back.'
"Jennifer was fuming when she looked at the activity on his page. 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?' "
When Jennifer confronted John about his behaviour, he had no choice but to admit he had been avoiding her.
The source added to Britain's Star magazine: "He didn't even deny it. He knew he was avoiding her. So, when she called him on it and ended things, he just said OK, and that he was sorry it didn't work out.
"He took the break-up like a man."
