This Steele is single! Dakota Johnson and her boyfriend Matthew Hitt have split, and the Fifty Shades of Grey actress is currently unattached, multiple sources tell Us Weekly.

Johnson, 25, and Welsh model/rocker Hitt were dating as of December. He was also mentioned in her recent first-ever Vogue cover story, but one source confirms that it's now over.

"Sometime over the holidays, they broke up," the insider tells Us. "Her life was getting too crazy and it wasn't something that he wanted to be a part of."

Indeed, Johnson has suddenly become a household name with her starring role as Anastasia Steele opposite Jamie Dornan's Christian Grey in the film adaptation of E L James' erotic novel Fifty Shades of Grey (which was released in theaters last Friday, Feb. 13).

As Johnson continues to become a red carpet fixture, her packed schedule was simply not conducive to maintaining a relationship. In the meantime, the Hollywood scion is casually seeing a few people.

Nevertheless, the source tells Us of her split from Hitt: "It wasn't a bad break."
