Nick and Vanessa Lachey are no doubt a competitive couple. However, the two will have to face each other when "Dancing With The Stars" opens a whole new season on Monday.

Although they have been married for six years, Vanessa admitted that she did not know what advantage she has over her husband when it comes to dancing. Nick, on the other hand, thought his wife is a better dancer than him but assured that he has his eyes set on the prize.

'DWTS' pairs tease friendly competition ahead premiere

For the upcoming "Dancing with the Stars" season 25, Nick and Vanessa Lachey will be paired with Peta Murgatroyd and Maksim Chmerkovskiy, who recently tied the knot.

The two couples even dubbed the exchange a "wife swap" and teased the fans on social media for the friendly competition.

Vanessa revealed that the four of them had set a goal to make it to the finals together. "We just don't want it to be awkward, like, week three that I'm sitting in the audience watching him and Peta [Murgatroyd] dance or vice versa," she added, according to Entertainment Online.

Nick thought it would be embarrassing to show up on the dance program if he and his partner would be kicked off from the competition earlier than the other pair. When asked who is better than the other, Vanessa jokingly claimed that she is a better singer compared to her husband.

Here's what to expect from 'DWTS' season 25

The Lacheys are among the 13 participating personalities for "Dancing with the Stars" season 25. Joining them in the ballroom are Nikki Bella with Artem Chigvintsev, Barbara Corcoran with Keo Motsepe, Derek Fisher with Sharna Burgess, and Jordan Fisher with Lindsay Arnold.

The new season will also feature Debbie Gibson with pro partner Alan Bersten, Frankie Muniz with Witney Carson, Terrell Owens with Cheryl Burke, Sasha Pieterse, Drew Scott with Emma Slater, and Lindsey Stirling with Mark Ballas.

The 13 pairs will be given four dance routines to choose from for their weekly performances. The "switch wife" duos are expected to perform cha-cha-cha for the opening week.

Carrie Ann Inaba, Len Goodman, and Bruno Tonioli will return as judges. Also, the dance program is reportedly eyeing to invite guest judges since Julianne Hough has confirmed her departure from the show three years after she was appointed as one the permanent judges.

Several sources stated that the two-time "Dancing with the Stars" winner had to give up her gig with ABC to focus on her acting career. An affiliate also clarified that Julianne Hough's departure has nothing to do with her marriage with Brooks Laich.
