Erika Jayne and Taye Diggs are ready to lip sync for their lives... and, more importantly, Christina Aguilera.

The Real Housewives of Beverly Hills breakout and the Broadway and film star will go head to head on an upcoming episode of Lip Sync Battle, which kicks off its fourth season this week.

While it's a secret so far which iconic Xtina song Jayne will perform (please be "Dirrty," please be "Dirrty"...), a special sneak peek clip reveals Diggs in nautical drag during his rendition of Aguilera's tongue-in-cheek 2006 swing-pop hit, "Candyman."

Watch below:

As for Erika Jayne, an Xtina-themed Lip Sync Battle performance is more than just perfectly on-brand for the vivacious pop star—it's practically fate!

In 2016, Saturday Night Live paid homage to the "Pretty Mess" singer with a RuPaul's Drag Race-themed skit featuring Chris Pine as a "Lip sync for your life!"-obsessed auto mechanic who gets down to Jayne's club banger "XXPEN$IVE."

Plus, the feeling between Jayne and Aguilera is mutual: In 2016, the music icon snapped herself singing along to the RHOBH star's "How Many F---s?," and later invited Jayne to perform at her December birthday bash.

Speaking to Jayne, the performer told us that seeing Xtina sing along to her song was "the ultimate compliment."

"One of the true voices of our era, singing along to my song? It doesn't get much better than that, really," she shared.

Watch Jayne and Diggs battle it out on Spike/Paramount Network Thursday, January 25 at 10 p.m. ET.
