Right out of college, Kostek was offered a job on ESPN's Saturday Night Football (2006), but turned it down for the opportunity to travel while modeling.
In 2013, while a junior at university, Kostek made it to the roster of the National Football League's (NFL) New England Patriots Cheerleaders.
In her last game as a professional cheerleader, she performed at the University of Phoenix Stadium in Arizona for Super Bowl XLIX where the Patriots beat the Seattle Seahawks on February 1, 2015.
Her ancestry includes Polish, Irish, and Panamanian/Jamaican.
Trained as a dancer, she often posts videos of herself on social media spontaneously dancing in places outside a dance studio. Her trademarked catchphrase, "Never Not Dancing" caught on and inspired others to do the same.
Graduated from Haddam-Killingworth High School in Higganum, Connecticut and majored in Communications at Eastern Connecticut State University.
