Fifty Shades of Grey star Dakota Johnson has reportedly split from her boyfriend Matthew Hitt.

Dakota's man felt her life was getting "too crazy" and thought "it wasn't something he wanted to be a part of," a source tells Us Weekly. 

The split comes just as Dakota's career went into overdrive with the release of her breakout film.

While the actress mentioned Welsh rocker Matthew in a Vogue interview published last month, it's thought the pair split up sometime around Christmas, just as the Fifty Shades publicity really began kicking off.

The film broke February opening weekend records at the US box office, and is already the most successful over 18's film ever in the UK and Ireland.

Given that Dakota's mum, actress Melanie Griffith, refused to see the film, it's no surprise her boyfriend got cold feet, too! However things ended smoothly for the couple, with the source admitting that "it wasn't a bad break."

Dakota doesn't seem too bothered anyway – she has apparently been casually seeing a few people already. Who knows, maybe she'll find her own Christian Grey?!
