The former One Tree Hill star struck up a relationship with Soffer last year (14), but now sources tell that their romance has fizzled out.

The insider says, "Sophia and Jesse just didn't work out. They dated for about a year and then grew apart. They're still friends though!"

Rumours of their relationship came days after her split from ex-boyfriend Google executive Dan Fredinburg, in August (14).

Fredinburg passed away in April (15), when he was one of 17 killed while scaling Mount Everest in Nepal as an avalanche tumbled down on them. After his death, Bush penned a touching tribute to her former flame on social media.

Bush previously dated her One Tree Hill castmates Austin Nichols and James Lafferty, and she was briefly married to Chad Michael Murray in 2005.
