Kat Graham has quit 'The Vampire Diaries'.

The 26-year-old actress has portrayed witch Bonnie Bennett on the show since its first episode in 2009 but has revealed that season eight will be her last.

She told US Weekly: ''Season eight will be my last season. I just hope that whatever I do after, the crew can come with me. If the crew can come with me, then we'll be good. The crew is going to be the hardest thing to let go, because we are a family.

''You know what, another season is a whole other year, and we're going to blow it out.''

However, before she leaves Kat's character will have a number of exciting storylines in the current season seven and the upcoming season eight.

She said: ''There's some really intense stuff with my character this season,'' the Hannah Montana alum says. ''I think the biggest episodes I've ever had are 20 [airing April 29] and 21 [airing May 6]. It's pretty major for the character - huge turns, a lot of stunts and cool s**t!''
