1. It was Dom's birthday on Monday!
Happy Birthday you beautiful man!
2. Katherine got all emotional in her beautiful birthday message to her co-star.
3. Matt also had some special words for his Parabatai.
Can you believe that 21 years ago today, @DomSherwood1 was born on a small farm in rural America. Now he's a star! Happy b-day, TV brother!— Matthew Daddario (@MatthewDaddario) February 6, 2017
We hope this joke goes on forever.
4. Dom had the cutest birthday companion!
Rajah has grown so much -- we remember when she was a tiny kitten.
5. And it was David's birthday too! He turned 21.
He's so young -- basically still a baby!
6. The birthday boy and Alberto were dressed to impress.
Wearing incredibly sharp suits is a key part of being a vampire!
7. Meanwhile, Harry was making interesting food choices.
We think that pizza might be slightly burned.
8. Will and Katherine took a trip to the aquarium together.
Katherine loves a good pun!
9. It's great to see Will fitting in so well!
We can't wait to see what his character is like.
10. Alisha gave us a wink!
Or maybe the sun was just shining in her eyes. Still cute!
11. Katherine keeps finding herself in gorgeous locations.
We really want that wallpaper.
12. And we got to see a BTS video of the Malec date!
We wonder who won that game of pool in the end...
