Katherine McNamara, it's your day!

In addition to winning the Female TV Star trophy at the E! People's Choice Awards earlier this month, the Shadowhunters: The Mortal Instruments actress has another reason to celebrate today...it's her 23rd birthday!

While we would love to spend our Thanksgiving—and McNamara's birthday—with the star, we are just thankful that the she regularly posts behind-the-scenes snaps from the set of her Freefrom hit on Instagram so we can feel like we are always with her.

In honor of the birthday girl, we invite you to come along with us and relive all the best moments from the Shadowhunters set before the show returns for the second half of its final season in 2019.

From posting selfies with her castmates to fun pics from the show's late-night shoots, McNamara loves to share what is happening on set with all the Shadowhunters fans and we can't get enough of her exclusive looks at all-things Shadowhunters.

Katherine McNamara Wins Female TV Star At the People's Choice Awards After Insane Fan Dedication

We love getting to see what it takes to make one of our favorite television shows and the Missouri native knows just how to make us all feel like we are true Shadowhunters insiders!

The Drexel University alum doesn't shy away from showing all aspects of the shooting process, from emotional cast table reads to the shenanigans in the hair and makeup trailer. She really takes fans along for the ride with her, which is why she definitely deserved to be dubbed a PCAs winner this year.

Check all of the 23-year-old star's best BTS Instagram posts below and be sure to wish McNamara a happy birthday before the day is done.

Green-Screen Goddess

"A lil #FrayFriday #fbf from @shadowhunterstv 3b for you angels... #shadowhunterslegacy."

Table Read Emotions

"Read a few words, shed a few tears, we're ready. I'm so grateful for the years with this kick-ass group of people. So much love in this room. Here we go again, Angels. #Shadowhunters."

Character Appreciation

"Happy birthday to this short, bad tempered, redhead. Thank you to everyone who has had a hand in bringing her story to life across page and screen. Clary has taught me so much. She is a loyal friend, an innovative artist, a brave daughter, a conflicted sister, a hopeless romantic, and a ferocious fighter. She is an imperfect hero but her mistakes make her grow. She is strong but with her chosen family she is unstoppable. I think the biggest lesson we can learn from her is be careful following blonde tattooed strangers into nightclubs on your 18th birthday... it just might change your life...Happy birthday, Fray. (Also, for those angels following along at home, #tbt #bts from ep 3x20) #Shadowhunters."
