The actress, who is best known for her role as Carmen Cortez in the 2000s film franchise, announced the happy news on her Twitter account, where she posted a picture of herself and husband Carlos holding a positive pregnancy test.
'PREGNANT! 🎉🎉🎉,' she wrote to her 459,000 followers. 'It’s #ClearblueConfirmed a lil blessing is joining the PenaVega fam! #ItsHappening #ClearbluePartner'
https://twitter.com/alexavega/status/743429032688025600Carlos also added a picture of his own, with a similarly overjoyed caption.
'Breaking news! It's #ClearblueConfirmed a lil PenaVega is on the way! #ItsHappening #HolyWow #ClearbluePartner', he wrote alongside the snap. He added on Instagram, 'There is going to be a new cool kid in town… And by cool I mean dorky just like their father.'
Fans were quick to send wellwishes to the pair, with one writing, 'That is so amazing!!! Congratulations!!!' and another agreeing 'I'm so happy for you!'
Alexa and Carlos got engaged in August 2013, whilst on a cruise with some friends, and tied the knot on 4th January 2014 in Puerto Vallarta, Mexico. Instead of Alexa taking Carlos' surname outright, they chose to blend their names into one.
The pair have since worked together on the film Spare Parts, which was released in 2015. Speaking at the time of the movie's release, Alexa said to Sonoma Christian Home, 'Having Carlos onset is like having the ultimate teammate.'
'We’ve both looked out for each other, and being on set together is fun and exciting. Honestly, our ideal situation would be to have a show like I Love Lucy so we could work together forever.'
