Mario Lopez is set to become a father again. The X Factor host has revealed he and his wife Courtney Mazza - who tied the knot in December after almost five years of dating and are already parents to two-year-old daughter Gia Francesca - are expecting their second child at the end of the summer.

The Extra presenter opened up about the news on the entertainment show on Tuesday after his daughter appeared on screen with a sign reading, "I'm going to be a big sister," saying, "I am the happiest father in the world. We cannot wait to welcome baby Lopez number two into our lives."

The family celebrated the news with a surprise baby shower, featuring balloons and lots of gifts from Carousel Designs. Mario previously revealed that he was looking forward to having more children. Before getting married the 39-year-old star said, "We're working on that. Right after the wedding. We'll wait for the guests to leave and then we're getting right on that!"
