Julianne Hough is bummed Chace Crawford dropped out of Footloose.

"It sucks," Julianne, 21, told at the ACMs in Las Vegas Sunday.

REVIEW: Gossip Girl's newest season

The former Dancing With the Stars pro -- who quit the show to focus on her singing and acting career -- says she may have to pull out of the '80s remake as well because of scheduling difficulties.

"His schedule couldn't work because of Gossip Girl and mine almost didn't work because of DWTS," Julianne tells Us, "so we're still actually working on mine to see if I can do it."

Does she miss DWTS? "I do and I don't," Julianne says. "I miss the camaraderie and dancing, but I'm busy doing my music. I'm touring with Sugarland this year. I have a single out in June."

Her bro Derek Hough is still competing. (His partner this season is Us blogger Nicole Scherzinger.)

After the show's premiere, Julianne went out to dinner with Kate Gosselin.

"It was crazy," says Julianne, who next stars in Burlesque with Cher and Christina Aguilera.

Julianne thinks that Gosselin gets a bad rap.

"I don't want to feel bad for her because she is a girl that is putting herself out there and good for her, but I have to say: I would be completely guarded and standoffish a bit," she says in the reality mom's defense. "Because you think everyone is out to get you.

"Once you break that, she is really great," she continues.
