Actress Amber Heard has split from her girlfriend, according to a report.

The blonde beauty started dating artist Tasya van Ree in 2008, when she 'came out' as a lesbian at gay rights advocate GLAAD's 25th anniversary bash.

Nevertheless, Heard and van Ree reportedly went their separate ways earlier this year.

A source tells In Touch magazine, "They are no longer in a relationship."

The split fuels rumors linking Heard to her The Rum Diary co-star Johnny Depp, who confirmed earlier this month that he and longtime partner Vanessa Paradis had broken up after 14 years.
