kat graham blonde vampire diaries 'Vampire Diaries'' Kat Graham goes blonde for Grammys 2013: But what about Bonnie?Triple threat Kat Graham is best known for her work as earthy witch Bonnie Bennett on “The Vampire Diaries.” Off screen, she’s got a lot more going on… and she ditched her natural dark hair color for an eye-catching new honey blonde look at the 55th annual Grammy Awards on Sunday night.

“Debuting a new look today. Lets see if they really do have more fun,” she tweeted on her way to the show, sharing the photo above with her fans. It’s not Graham’s first time trying out life as a blonde — she wore blonde curls to a Wango Tango concert back in May.

And even though Graham’s got golden locks off-screen, word is that Bonnie’s hair won’t be changing any time soon! The wig that Graham wears on-screen for her day job won’t be getting a new dye job.

Graham is attending the awards as a correspondent for E! — she’ll be co-hosting their Grammy After Party, a post-show recap, at 11:30 p.m. EST.
