Selena Gomez‘s BFFs know her well!

For the pop star’s 27th birthday, two of her best friends surprised her with a visit to the set ofShark Tankin September — which just so happens to be Gomez’s obsession.

“Not many of you know but I am obsessed with shark tank. Two of my best friends nailed my gift 😁,” Gomez wrote in the caption for avideo of the momentthey surprised her.

The video — which features snippets fromThe Office,Friendsand aTaylor Swiftmusic video — seems to culminate in a happy birthday message from none other than Mark Cuban, one of the show’s “sharks” (but the real surprise comes moments later).

“Hey Selena, it’s Mark Cuban from Shark Tank, I wanted to say happy 27th birthday,” the businessman says in the clip.

Gomez gives an audible gasp when Cuban, 60, comes onto the screen and afterwards says, “That was so cool!” But little did she know that the best part of the surprise was still to come.

The video continues, showing theShark Tanklogo with a photo of Gomez photoshopped on top.

“SHARK TANK X SG,” the screen says. “WE’RE GOING TO THE TANK IN SEPTEMBER.”

Andthat‘sthe moment that Gomez truly freaks out with excitement.

“No! We are?” Gomez shouts, turning to her friend with a huge smile on her face before jumping off the couch and covering her mouth in surprise. “Oh my gosh, I’m so excited!”

Gomez seems to be having a great start to her new year, which she rung in with agetaway in Italy.

“Well I’m 27 now,” the “Wolves” singer wrote on Instagram last week, along with agorgeous shot of herself in Italy. “I wanted to thank each and every one of you for your words on my bday,” she added in gratitude to her fans.

“Not just the quick notes,” she added. “The thought that goes behind every word you write usually ends up with me crying grateful tears like I did last night. Praying for all of you!! I LOVE YOU.”

Over the weekend, she posted another stunning photo from her trip — in which hermeaningful semi-colon tattoois in full view — writing in the caption, “Me, Italy -trying desperately to look like a Fellini film.”
