Several news sources are reporting that Zac Efron and Lily Collins have quietly ended their brief romance. The private couple were only photographed together once and kept their relationship low-key.

The 24-year old Lucky One actor and the 23-year old Mirror Mirror actress, who have only been dating for about three months, were reportedly not in a serious relationship, and their busy schedules did not help to strengthen their romantic feelings.

Efron, who is currently in talks to star in Johnny Quest, was previously in a five year relationship with Vanessa Hudgens, his costar in High School Musical. He was also linked to Taylor Swift.

Collins, daughter of legendary singer-songwriter Phil Collins, ended her relationship with Abduction costar Taylor Lautner in September 2011. She will be appearing in Writers in 2013 and will have a starring role in The City of Bones which is due to premiere later in 2013.
