Zac Efron is apparently back on the market after splitting from actress Lily Collins.
The Lucky One star and the Mirror Mirror actress had been dating for a few months but have now parted company after the relationship "fizzled", reports Us Weekly.
A source told the magazine: "They're no longer together. They were never serious, though; it was just a casual thing and it fizzled."
It's thought that their busy schedules made things harder for Zac, 24, and 23-year-old Lily, whose dad is singer Phil Collins.
The insider went on: "They were never in the same place at the same time."
Lily previously dated Twilight hunk Taylor Lautner, her co-star in Abduction.
meanwhile Zac was in a long term relationship with Vanessa Hudgens, whom he met on the set of High School Musical.
