Alexa PenaVega & Carlos Pena Jr – ‘Dancing With the Stars’ Season 21 Contestants

Alexa PenaVega & Carlos Pena Jr.

Alexa PenaVega and husband Carlos Pena Jr. are the first married couple to ever compete on Dancing With the Stars. This husband and wife duo are both actors and music artists who are competing against each other for season 21 of DWTS. Carlos' pro partner this season is Witney Carson, while Alexa's is Mark Ballas. Both of their pros are winners in the ballroom, so this could go very well for either of them. While Carlos is known for his role on the TV show Big Time Rush, Alexa is known for her part in the Sky Kids movies. Alexa and Carlos got married on January 4, 2014 in Puerto Vallarta, Mexico. Now, the two have combined their last names to create the PenaVegas. Alexa was previously married to film producer Sean Covel on October 10, 2010 and the marriage lasted about two years.
