'Sweet 15: Quinceanera' Star Bursts Into Tears After Her Friend Collapses in Premiere Sneak Peek

It's her party and she'll cry if she wants to! The girl of the hour breaks down at her lavish 15th birthday party in Sweet 15: Quinceañera's series premiere on Tuesday, September 27, as seen in Us Weekly's exclusive sneak peek.

The TLC unscripted series focuses on cousins Alexis and Jarling, who plan parties and own a dress show in Miami. The preview clip shows the team throwing an unforgettable bash for one lucky birthday girl, Anna Marie.

"Everyone's having a great time at the party — they're enjoying their dinner, and Anna Marie is going to change into her after-dress," Alexis tells the camera. "It's kind of a new thing where girls are going to change into a different dress to be able to dance and party with their friends."

However, things take a dramatic turn when a guest falls to the ground, and someone shouts to call 911.

"This is one of the most important days in Anna Marie's life, and one of her guests has just collapsed," a party planner says.

The drama leads Anna Marie to get emotional as she says through tears about her pal, "I want her to be OK — I don't care about anything else."

This season features birthday parties that will include a bikini photo shoot, an alligator, a Diamonds Are Forever theme and even a quick trip to Paris. Exotic cars and costume changes will also be par for the course, naturally.

Watch the drama unfold in the clip above. Sweet 15: Quinceañera premieres on TLC Tuesday, September 27, at 9 p.m. ET.
