Josh Hartnett Single

Hollywood heart-throb Josh Hartnett is single once again after parting ways with his childhood sweetheart Ellen Fenster.

The pair, both 25, had been together for a number of years and about a year ago, they bought a $2.5 million mansion together in their native Minneapolis, Minnesota.

But a source now tells American magazine the Star, "They just broke up. He seems okay."

Pals are staying tight-lipped on why the two decided to go their separate ways after so many years.
