January 21 is the new October 3.

It was announced last weekend that Jonathan Bennett, best known for playing Aaron Samuels in the hit 2005 comedy Mean Girls, will be competing in the second season of Celebrity Big Brother on CBS.

"If you see this picture that means I am officially locked away going on the next adventure in my life," Bennett, 37, captioned a packing photo on Instagram.

Bennett, who has competed on Dancing With the Stars, regularly hosts Food Network competition shows like Cupcake Wars, Cake Wars, and Halloween Wars.

He revived his Mean Girls character last year for Ariana Grande's "Thank U, Next" video and recently reunited with co-star Lindsay Lohan on the after show for her new MTV reality series, Lindsay Lohan’s Beach Club.

Bennett revealed publicly in 2017 that he is dating Amazing Race and Chippendales alum Jaymes Vaughan.

Referencing the empowering anthem “This Is Me” from The Greatest Showman, one of his favorite movies, Bennett tells ET Canada he's excited to do Celebrity Big Brother because the world "can see that this is me... This is who I am."

"How many times do you get to ever be locked away from the world, make money, do fun things for your career, and, like, be with celebrities that you would never get to talk to?" he continues. "I don’t know who’s in the house yet, but I know they’re going to be rock stars, musicians, athletes, the people that are the top of the top in each of their fields. You’re put in a house together and get to spend a month with them, getting to know them, like, how fun is that?"

"Get me off the grid, lock me in there with whoever it is, and let’s make a TV show."

Bennett, who was "obsessed" with the show last season, is also pumped about the Big Brother games. “I am a giant toddler," he says, adding that he and his friends play summer camp-inspired games like “Can You Eat a Banana Through a Pair of Pantyhose?”

“I’m going to go in and have so much fun and just try to make friends with everyone, because that’s what I do in my normal life,” he says of his non-strategic strategy. He also plans to “float like a butterfly” until the final four, when he’ll “sting like a bee.”

"I’m going to try really hard not to annoy people because I talk a lot," he admits. "It’s not like I’m annoying, I just have a lot of energy and some people can’t handle that at 8 in the morning, so we have to know when to turn it down a little bit."

Hairspray's Marissa Jaret Winokur won last year's inaugural U.S. season of Celebrity Big Brother, and RuPaul’s Drag Race judge Ross Mathews was the runner-up.

"My strategy going into the house," Bennett clarifies in an Instagram video, "is to go in, float as long as possible, just like Ross and Marissa did, become friends with everyone, not win too many of the HOHs so I keep the target off of my back, and then do what Marissa advised me to do, which is take in sweatshirts, because it’s very cold in there, use them as collateral to go around and buy peoples’ alliances, ’cause girls are always cold."

Does Bennett have any fears about the competition? “I am a zit-popper,” he tells TV Guide. “I know I’m going to get caught popping a zit on national television on the live feed, and that’s fine.”

Bennett will be joined on Celebrity Big Brother by Dina Lohan, former White House communications cirector Anthony Scaramucci, actor Joey Lawrence, Olympic swimmer Ryan Lochte, personality Kato Kaelin, Real Housewives of Atlanta's Kandi Burruss, singer Tamar Braxton, actor Tom Green, former WWE star Natalie Eva Marie, Olympic hurdler Lolo Jones, and former NFL player Ricky Williams.

Celebrity Big Brother premieres January 21 on CBS.
