Jennifer all of a Twitter over lover's online 'romance'

Jennifer Aniston apparently split from toyboy John Mayer after she discovered there was a third party in the relationship – Twitter.

She ended the rollercoaster romance after finding out he spent hours on the social networking site, despite claiming he was too busy to call her, according to pals.

'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”,' a source said.

But the 31-year-old's flimsy excuse was exposed when the actress, 40, noticed his regular updates on Twitter.

'Jen was fuming,' her friend added.

'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 e-mail, make a call?”.'

The pair started their on-off affair in April and appeared inseparable again at the Oscars last month.

Shortly after the split, Mayer's Twitter update read: 'This heart didn't come with instructions.'
