Jennifer Aniston has reportedly told friends it was her decision to end her romance with rocker John Mayer.

The singer-guitarist was rumoured to have dumped the former Friends actress last week after she returned from promoting her latest movie Marley & Me in Europe.

But, according to U.K. newspaper The Sun, it was Aniston's decision to end the relationship - after Mayer became distant following an appearance at the Academy Awards last month.

A source tells the publication, "They had a great time at the Oscars, but he seemed to go cold right after. It's humiliating. To say her feelings are hurt is an understatement."

The pair had a tumultuous relationship - they started dating in early 2008 but parted ways during the summer. They rekindled their romance in October, before reportedly splitting again last week.
