The stars were out in full force at the 87th Annual Macy's Thanksgiving Day Parade in New York City.

Ariana Grande, Jimmy Fallon, Austin Mahone and more were all driven on floats throughout the city streets.

Grande performed "Last Christmas" while doing her best to stay warm.

She looked adorable in her winter coat and accessorized with a pair of white fuzzy ear muffs.

"Happy Thanksgivinggg my loves…Wishing you a beautiful holiday with your families and loved ones. I am so thankful for you," she tweeted.

Mahone sang his hit "Banga Banga" to tons of fans and also took to social media to thank everyone for coming out to see him.

"That was so much fun!!!" he wrote. "My face is frozen tho…"

Meanwhile, The Roots and several furry friends from Sesame Street joined Jimmy Fallon on his special float.

Elmo, Cookie Monster, the Count, and of course, Big Bird, all joined in to sing "Somebody Come and Play."

The talk show host joked Wednesday on Twitter, saying, "I'm on the Sesame Street float in the parade…But it'll be awkward when Big Bird asks, ‘What're you having for dinner?'"

And they weren't the only famous faces braving the freezing temperatures.

Fifth Harmony, Pete Wentz, Cher Lloyd, Kellie Pickler, Megan Hilty and Kristin Chenoweth were also special guests of the event.
