Happy birthday, Nina Dobrev: Celebrate with 'The Vampire Diaries' best Katherine moments - GIFs


Happy birthday, Nina Dobrev!

"The Vampire Diaries" star turns 25 on Thursday (Jan. 9), and she's earned all of the presents for her work on Season 5 playing not one, not two, but three main characters ... even in one scene. Seriously, Dobrev's acting is on par with "Orphan Black's" phenom Tatiana Maslany. Give this girl some awards, stat! Oh, thanks for getting the memo, People's Choice Awards.

While we don't have control over the accolades Dobrev should be receiving, we can celebrate her birthday in style -- by reliving all of her sassiest moments as Katherine on The CW's supernatural drama in GIF form, of course.

The first time we ever met Katerina Petrova -- in the present, not in flashbacks -- was the end of the Season 1 finale, after we thought it was actually Damon and Elena making out for the first time. We found out just a few minutes later it wasn't actually human Elena that Damon was locking lips with, but Katherine pretending to be Elena. How did we find out it was the 500-year-old vampire on-the-run? She cut of John's finger and stabbed him with a kitchen knife. Ouch.

In Season 2, everyone thought they were safe from her diabolical ways after Katherine was compelled by Elijah to stay in the tomb under the church, which was where everyone thought she was for all of Season 1. But little did they know once they daggered the Original, the compulsion would wear off. 

Well, Katherine knew. Katherine always knows. Damon's face when he realized that was not his girlfriend Andy Starr naked in his shower said it all:

After Klaus compelled Katherine not to leave his apartment, Damon snuck her some vervain so she didn't have to follow any more of his orders. That meant she could break into his whiskey stash and have her own one-woman-party while the big bad hybrid was out. Just because she's a captive doesn't mean she doesn't know how to have fun:

In flashbacks to when Katherine was still a human, she's actually a sweet girl who still believed in love. This was also when her tumultuous relationship with Elijah began, though it didn't blossom until much later.

Katherine's a survivor. How has she lasted this long with the amount of enemies she's stabbed in the back over the years? She keeps moving forward, with one crucial rule:

But she sometimes comes through and saves the day, like bringing Klaus' blood -- the cure for a werewolf bite -- to save Damon's life instead of keeping it for herself for a rainy day. Of course, that didn't stop her from delivering some A+ snarky advice:

And then there was that time she killed Jeremy, stole the cure, and woke Silas up .... oops. At least Jeremy is alive again and Silas is dead, so .... silver lining? And the cure got shoved down her own throat, so karma and all that:

The girl gets around. She's been romantically linked with just about every hot guy on the show, and she takes pride in it -- even if everyone else doesn't:

So happy birthday, Dobrev, and cheers to you, Katherine: let's hope you make it through the 100th episode of "The Vampire Diaries" alive.

"The Vampire Diaries" 100th episode airs Thursday, Jan. 23 at 8 p.m. ET on The CW.
