Bailee Madison Was ‘Bursting’ Over Hailee Steinfeld At Y100’s Jingle Ball 2015

Hailee Steinfeld lit the stage on fire at Y100’s Jingle Ball 2015 held at BB&T Center on Friday night (December 18) in Sunrise, Fla.

The 19-year-old actress and singer hit the stage along with Tove Lo, The Weeknd, Zedd, and Chloe Angelides to close out the Jingle Ball tour — and her BFF Bailee Madison just lost her cool over Hailee‘s performance!

“I’M BURSTING WITH HAPPINESS! #y100jingleball @iheartradio @HaileeSteinfeld LOVE YOU HAILEE SO PROUD OF YOU,” Bailee wrote with a short vid on Twitter.

She added later on, “Watching u on stage was a moment I’ll never forget. You my dear friend, are the brightest light. @haileesteinfeld.”
