"I’m not going to be dancing, but I can finally announce that I am coming back on to judge," the 28-year-old actress told ET's Denny Directo. "I’m excited."
The Grease: Live star took off season 22 to work on the hit Fox musical event, and it paid off. The production netted 10 Emmy nominations and brought Julianne some meaningful friendships.
"Not only was it such a monumental thing for us to accomplish, but I mean the friendships are lifelong," she explained "It's incredible."
"I'll be doing Dancing With the Stars and Hairspray at the same time and going back and forth, so it should be fun," Derek told ET at the Creative Arts Emmys.
"She loved the experience so much and so, for me, seeing that really encouraged me to take that role," Derek explained.
Another role Derek recently took on was the lead in Singin' in the Rain on Broadway. However, it appears that he'll have to wait a while before that kicks off, as the production is currently on hold.
"I'm not sure what exactly is going to be happening, but it's definitely in my future," Derek said.
While Derek might be waiting a while to hit the Broadway stage, fellow DWTS pro Mark Ballas is headed to New York City soon to star in the final months of Jersey Boys.
