What You Need to Know About Selena Gomez's Adorable Little Sisters

Selena Gomez grew up as an only child, but—much like the Fresh Prince of Bel Air—her life got twisted upside down in 2013...and then again in 2014.

Selena's mom Mandy Teefey and her second husband Brian Teefey gave birth to their daughter Gracie Elliot Teefey in June 2013, and then—almost exactly a year later in June 2014—Selena's dad Ricardo Gomez and his wife Sara welcomed their daughter Victoria. So now Selena has two adorable little sisters to dote on and we are living for all the cute pics, especially the ones of Selena and Gracie twinning at the Frozen 2 premiere this week. Here's what you need to know about Selena's special bond with 6-year-old Gracie and 5-year-old Victoria:

Selena is super attached to Gracie, and we can see why. "She’s adorable," Sel told E! News shortly after Gracie's birth. "I’m obsessed with her and becoming a big sister. I know I’ve had the responsibility to be a role model for girls but, when you have a little sister of your own, you kinda think, 'Okay, this is legit.'"

More recently, Selena explained how Gracie brings out her maternal side, "I keep her very very protected. I mean, it's instinctual."

Makes sense, wouldn't you be overprotective of this little angel?!

For some sister-sister bonding, Sel took Gracie to the Frozen 2 premiere on November 7, and they even wore matching dresses and sequin feather capes. It is truly the cutest thing you'll ever see:

"I will forever let my sister know she is strong, bold and beautiful," Sel wrote in the caption of the video. "She will be raised to know her voice matters. She is going to understand the importance behind being a leader and inspire others by her truth."

Selena's mom Mandy suffered a miscarriage before welcoming Gracie, and wrote a now-deleted Instagram post explaining that she named the baby Scarlett:

Thank you to all the fans who honored our Scarlett yesterday. Dec. 17th will never be the same, but we decide to celebrate her by writing her letters on red balloons and releasing them...Fans, I want you to know you are family because I have a huge family and you are the only ones who remember! XO forever.

Clearly Selena learned the importance of family from her mom! Check out a few more photos of her and Gracie bonding up a storm and feel free to tear up. Unless you're secretly reading this at work/school and your boss/teacher is side-eying you right now, in which case KEEP IT TOGETHER, GUYS.
