Dancing With The Stars is about to get a bit Fuller, and more modelesque: Fuller House star Jodie Sweetin and America's Next Top Model's most recent winner, Nyle DiMarco, will join Season 22, Good Morning America and E! News have reported, respectively.

Mischa Barton, best known as Marissa "oooh what-cha saay-aaay" Cooper on The O.C., has also joined next season's lineup, US Weekly reports. Also signed on: Kim Fields of RHOA and Facts of Life — and the full cast will be revealed March 8 on GMA.

On GMA, Sweetin said she'd been approached to compete on the show in the past, but that Fuller House filming didn't permit it. A lifetime lover of dance, she noted she's ready to put her skills to the test now that she's officially set to compete.

"Stephanie was a dancer on [Full House] growing up, I danced growing up," she said. "I definitely don't call myself a professional — I have some experience, I have some rhythm, so I think I'll be okay."

Sweetin's addition to the cast is a bit of a tradition-in-the-making for her TV family: In 2014, Sweetin's Fuller House co-star Candace Cameron Bure competed on DWTS Season 18, in which she placed third. Amy Purder, a snowboarder, came in second and Meryl Davis, an Olympic ice dancer, won.

DiMarco, ANTM's final winner, will be the show's second deaf contestant. Oscar-winner Marlee Matlin competed on the show's sixth season in 2008 and placed seventh.

DWTS Season 22 will premiere on ABC on March 21.

And more TV News: Sweetin's Fuller House has officially been renewed for a second season, the show's Twitter account posted this morning (March 2) with the video below. The first season made its Netflix debut on February 26.
