Everyone knows that a very important part of being in a relationship is remembering dates: birthdays, anniversaries, etc. And it looks like Ian Somerhalder (Damon Salvatore) is on top of his game! 

Today is Vampire Diaries star Nina Dobrev’s (Elena Gilbert) 24th birthday, and Ian tweeted a birthday wish to his lady love at 12:46 a.m.

You Jules are correct! Happy Birthday beautiful @ninadobrev! RT @julieplec: Am I wrong or is it the gorgeous @ninadobrev's birthday?!!!”

We wonder what the happy couple will do to celebrate. Perhaps they’ll share a gluten-free cake on the way to the People’s Choice Awards tonight?

Happy Birthday, Nina!
