British pop star Sarah Harding has split from her music producer boyfriend after two years together, according to a report.

The former Girls Aloud star has broken up with Mark Foster due to her gruelling schedule shooting scenes for U.K. gymnastics-based reality Tv show Tumble.

Foster has now moved out of the home the couple shared in Buckinghamshire, England, according to The Sun on Sunday newspaper.

A source tells the publication, "As training has intensified for the show they have seen less and less of each other over the last few weeks. She has been training twice a day and they have not really had a chance to spend quality time together."
