Jennifer Hudson has a very tight schedule these days. When the “American Idol” alum is not rehearsing for NBC’s ”Hairspray” live adaptation, she is preoccupied with the preparations for the premiere of “Sing” in Los Angeles this weekend.

To give a peek at how busy she is, Hudson took to social media on Wednesday to share a couple of snaps and clips from her back-to-back rehearsals. On Instagram, she shared a snap with her “Hairspray Live!” co-star Garrett Clayton as they pose for the camera while wearing hats. Hudson revealed in the caption that her co-actor actually gifted her the hat she’s sporting.

If it wasn’t obvious to fans that she was at the set for the rehearsal of “Hairspray Live!,” Hudson also shared another photo with her musician friend and band member Dave Jackson in between rehearsals. She uploaded as well a video clip on her Instagram telling in her fans that she is on the set though she’s feeling jet lagged after flying to the U.S. straight from her judge duties for “The Voice U.K.” Joining her in the clip is Unissa Cruse-Ferguson, the winner of the “Hairspray Live!” audition in Baltimore City, according to WBAL TV.

Prior her “Hairspray Live!” rehearsals, Hudson shared in her earlier posts that she also practiced for the premiere of the movie “Sing” in LA. She also teased her fans if they could identify her voice in the film. “I can’t wait to see if u guys can pick my voice out in the film! I’m looking forward to this!” the Oscar winner wrote.

“Sing” is having its red carpet premiere in LA this Saturday, Dec. 3. The animated movie has an ensemble cast that includes Hudson, Matthew McConaughey, Reese Witherspoon, Seth MacFarlane, Scarlett Johansson, Taron Egerton, John C. Reilly and Tory Kelly. It is slated to hit cinemas on Dec. 21, according to Average Socialite.

Meanwhile, Hudson’s “Hairspray Live!” co-stars include Harvey Fierstein, Derek Hough, Martin Short, Ariana Grande, Andrea Martin, Dove Cameron, Kristin Chenoweth, Rosie O’Donnell, Billy Eichner and Clayton. The live musical adaptation of the 2002 hit Broadway show is scheduled to air on NBC on Dec. 7.
