Actress Julianne Hough and her TV presenter boyfriend Ryan Seacrest have reportedly split.

Safe Haven star Hough and the American Idol host have ended their romance after two years of dating and are no longer living together.

A source tells UsMagazine.com the relationship suffered due to their gruelling work schedules.

The insider explains, “Honestly, their schedules were too hectic. It just got to be too much. I think they both just sort of knew they couldn’t do it anymore. The travel and lifestyle got to be too much. Who knows if this is just for now, but I think this is for good.”

Neither star has commented on the rumours, but on Friday Hough tweeted a photo of the inspirational motto “It gets better!”

The break-up caps off a rough few days for Hough - the blonde beauty was the victim of thieves last Friday when $100,000 worth of jewellery was stolen from her car. She was then left with swollen “chipmunk cheeks and Botox looking lips” after root canal surgery.
