The 9-1-1 star and his fiancée, Chrysti Ane, welcomed their first child together, a baby boy named Mateo, on Thursday. Guzman's brother, Steven, shared the exciting news on his Instagram, posting the first photos of the proud parents and their new bundle of joy.
"Mateo Lopes Guzman. When I saw you I had tears of pure happiness and knew my life just got better," Steven wrote alongside the slideshow. "I promise to love you until the day I die and be the best Tio you could ever dream of. Only thing I don’t like about you is that you’ve easily taken the throne of cutest Guzman alive. 1-24-19 is a proud day for us all."
Steven also shared that baby Meteo was 6.5 pounds and 19 inches long.
Ryan, 31, and Chrysti, 25, announced the exciting news that they were expecting back in September. Since then, the Power Rangers Ninja Steel actress and fitness guru hasn't been shy about documenting her first pregnancy journey with her fans on social media:

But we're both very, very excited. We can't wait."
