Sophia Bush splits from boyfriend - report

Actress Sophia Bush has reportedly split from her boyfriend, Google programmer Dan Fredinburg.

The former One Tree Hill star and the tech engineer called it quits back in February (14), according to Us Weekly.

An insider claims they "still really care a lot about each other but it was impossible to retain a romantic relationship with the careers they have."

Bush and Fredinburg first went public with their relationship last year (Apr13) when they were spotted cuddling and holding hands at the Coachella Music Festival in California.

Earlier this year (Apr14), Fredinburg suffered a mountain climbing scare after he narrowly avoided a deadly avalanche in Mount Everest.

At the time, a relieved Bush told E! News that her beau was safe, but the incident "was obviously really scary for all of us who love him and love everyone on the trip."

Bush, who is currently shooting cop drama Chicago P.D. on location, previously romanced her One Tree Hill co-stars Austin Nichols and James Lafferty, and she was briefly married to Chad Michael Murray in 2005.
