Alexa and Carlos's third child, a daughter named Rio, was born on May 7, a month earlier than expected. Both parents announced Rio's birth on Instagram, writing: "Little Rio could not wait to come out and play with her brothers! Momma is feeling good and baby girl is kicking some serious booty in the NICU. Praying we can all be home together very soon! What a wave of emotions. Much love and thanks to all the Nurses, Doctors from Maui to Oahu - who brought little Rio safely into this world."
