Jennifer Aniston reportedly dumped boyfriend John Mayer because of his obsession with social networking website Twitter.
The pair ended their romance earlier this month (Mar09), with some reports alleging it was Mayer's decision to break up.
But, according to U.K. magazine Star, Aniston ended the relationship after discovering Mayer was spending hours posting updates on Twitter.com, despite claiming he was too busy to get in touch with her.
A source close to Aniston tells the publication, "Jen was fuming. There he was, telling her he didnt have time for her and yet his page was filled with updates! Every few hours, sometimes minutes, hed update with some stupid line.
"She was like, He has time for all this Twittering, but he cant send me a text, an email, make a call? He didnt deny it. He knew he was avoiding her. So when she ended things, he just said OK, and he was sorry it didnt work out.
