According to reports, actor Kellan Lutz has split from his longtime girlfriend Sharni Vinson.

The Twilight hunk who previously dated AnnaLynne McCord on and off from 2008 to 2010, has been dating Australian beauty since 2011, but the pair went its separate ways earlier this month, according to

Lutz met Vinson, who was previously linked to CSI: NY star A.J. Buckley, while auditioning for Step Up 3D. Vinson landed a starring role in the movie, unfortunately Lutz did not.

The 28 year-old actor, who is best known for playing vampire Emmett Cullen in the Twilight series, recently heaped praise on Vinson's romance skills after they enjoyed St. Valentine's Day together in February, saying, "Let's just say that I did it so well that she was surprised that I didn't propose to her."

Lutz isn't the only bloodsucker to have his heart broken recently - Vampire Diaries co-stars Ian Somerhalder and Nina Dobrev have broken up after three years.
