It was a big love fest on the Atlanta set of the Vampire Diaries this week!

Gabby Douglas was there to film a cameo on her favorite show--and the cast freaked out that their favorite Olympian was in their midst!

Nina Dobrev freaked out about what to wear and Ian Somerhalder took a bite--literally--out of Gabby's prized gold medal!

Sadly, Kat Graham, a huge Gabby fan, was so sad to be off set that day and miss out on meeting Gabby too.

Check out the video above for deets and scenes from the set--and tune in for Gabby's episode on November 29th!
