Los Angeles - Emma Watson has split from her long-term boyfriend.
The Harry Potter actress and William Adamowicz met when they were both students at Oxford University in the UK, and it has been confirmed they broke up during the summer.
Mail Online reported that news of the break-up preceded eyebrow-raising pictures of Adamowicz, 23 - taken during a New Year party in New York - being uploaded on to social networking site Facebook.
"The Oxford graduate is seen with white powder spread across a table in front of him," Mail Online reported.
A spokesperson for Watson told the Sunday Mirror newspaper: "Emma and Will separated last summer and are no longer in touch."
The former couple were spotted together in November at an acoustic folk rock concert, but their romance is said to have been over months earlier.
According to reports, the 23-year-old star's hectic film schedule was the reason for their break-up as she tries to find the balance between her education, personal life and movie career.
It was recently said Emma was looking to focus on her academic studies at Brown University in Providence, Rhode Island, US, where she is studying English.
