Find Out What The Shadowhunters Cast Did On Valentine's Day!

Plus see how Alberto and Isaiah celebrated their birthdays.

This week's best cast moments.

There was so much excitement this week! Alberto's birthday was on Valentine's day, which is appropriate because everyone loves him, and his character is a true romantic at heart. Everyone was sharing the love, including Valentine himself. Isaiah had his birthday this week too so there was definitely a lot of celebrating to be done. We just can't get enough of this cast!

1. Happy Birthday to the cutest Vampire there's ever been.

2. Katherine had a lovely message for her co-star.

She never forgets birthdays, she's so thoughtful.

3. And Jade sent him some love too.

Amazing shades, Alberto!

4. Romance was definitely in the air.

Sending all of the #ValentinesDay love to our Shadow Fam. 🖤
