It takes two to tango!

After Chris Soules gives out his final rose on The Bachelor finale, he'll partner up with a different woman as the 12th contestant on season 20 of Dancing With the Stars, Us Weekly has confirmed.

When the celebs competing on the 20th edition of the ABC dance competition were announced on Good Morning America Feb. 24, one name was missing — the star partnered up with dance pro Witney Carson.

DWTS host Tom Bergeron said at the time, "Her partner couldn't rose — I mean rise so early to be here," and now Us can confirm that his misspeak wasn't just a slip of the tongue.

A source told Us Weekly that Soules has been meeting with DWTS producers over the past few weeks to understand what, exactly, his run on the show will entail. He even called fellow Bachelor Sean Lowe — a Dancing With the Stars alum — for advice.

"He seems like he’s not totally sure what he’s getting himself into! It will be fascinating to see how well he does," the source said.

Soules' partner, reigning champion Carson, who took home the Mirrorball trophy with Alfonso Ribeiro in season 19.

Other celebs competing for the title include football star Michael Sam, Olympic gymnast Nastia Liukin, legendary singer Patti LaBelle, Shark Tank's Robert Herjavec, Glee actor and singer Riker Lynch, model Charlotte McKinney, U.S. army vet and amputee Noah Galloway, LMFAO's Redfoo, actress Suzanne Somers, and Bruce Willis and Demi Moore's daughter Rumer Willis.

Soules joins the Bachelor-Dancing With the Stars crossover club alongside pal Lowe, fellow Bachelor Jake Pavelka, Bachelorette Trista Sutter, and Bachelor 13 castoff Melissa Rycroft.

Tune in to the Dancing With the Stars season 20 premiere on Monday, March 16 at 8 p.m. on ABC.
