Hayes Grier enjoys a sweet ice cream cone while taking a break from rehearsals on Sunday (October 18) in Los Angeles.

The 15-year-old Dancing With the Stars contestant has been busy practicing with his partner Emma Slater.

The following day, Hayes performed a jazz inspired by Grease‘s famous track “You’re the One That I Want.”

“I’m just going to put it out there, @HayesGrier you were a 10 tonight in my book, I can’t believe the transformation. You were brilliant,” Emma tweeted after the show.

FYI: Hayes is wearing a Target shirt.
