Lily's first boyfriend Riley Harper is a handsome guy. According the information that I have,it shows they met on the set of Priest. And their relationship started in 2009 and broke up in 2010. Riley is an actor,but he is not famous enough,I guess this is the reason why Lily broke up with him.
Lily's another ex. boyfriend is Taylor Lautner. They met in Abduction set. Everyone know Taylor Lautner is the best boyfriend in the world,so do you know why Lily chose to dump Taylor. Someone said Lily wanted to be the leading role of the movie of Snow White. Kristen Stewart also wanted the same role,so Lily got mad and she said Taylor helped Kristen overly. In addition,I believe everyone know Kristen is one of Taylor's best friend and Kristen already has a handsome boyfriend. But Lily was really willful and she dumped Taylor Lautner immediately.
Their relationship started on November 2010 and broke up on September 2011.
Lily's third ex. boyfriend is Zac Efron. Their relationship started on February 2012 and separated on May 2012. They have the same agent maybe it is the reason why they start dating. Their friends said they were not intense in this relationship. Maybe Zac still misses Vanessa Hudgens.
