It's time for some marital bliss in the ballroom!
Married couple Alexa and Carlos PenaVega will compete on season 21 of Dancing With the Stars, ET exclusively and officially reveals.
Alexa, 26, best known for her big-screen role in Spy Kids, and her husband, 26-year-old actor and singer Carlos (Big Time Rush), will be the dancing competition's first married duo to compete against each other on the series.
ET caught up with the dancing duo at Disneyland's Diamond Celebration on Thursday morning to break the DWTS news.
"It's so exciting," Alexa, who is also celebrating her 27th birthday today, gushed to ET's Cameron Mathison. "It's beautiful, it's overwhelming, it's an incredible blessing."
Alexa and Carlos, who tied the knot in January 2014, will be paired up with separate professional partners and will dance against each other for the mirror-ball trophy. However, the couple is determined to support each other throughout the process.
"It's so good, though, because he literally rehearses right next door," Alexa shared. "So he'll walk over to me and he'll just give me a kiss. It's just so encouraging. He is my teammate and my life partner, so I like that encouragement. I need it."
Carlos confessed that there was one very important reason why he accepted ABC's invitation to dance on season 21. "The opportunity to work with my wife was like kind of almost a number one because we love spending time together," he said. "We're almost two years married. It's still fresh. I was like, 'Babe, we got to do this' and here we are."
Back in season eight, Jewel and her then-husband Ty Murray, were set to be the first-ever married couple to perform on the series, but due to the singer's injuries in week one rehearsals, she was forced to drop out of the series. Jewel was later replaced by former Playboy model Holly Madison.
It was previously announced that DWTS' season 21 lineup will feature Backstreet Boys' Nick Carter, Bindi Irwin, the daughter of late Crocodile Hunter Steve Irwin, and Triple Crown jockey Victor Espinoza.
The remaining DWTS contestants will be revealed on Wednesday, Sept. 2 on Good Morning America and Dancing With the Stars premieres Monday, Sept. 14 at 8 p.m. ET on ABC.
