Mario Lopez Daughter Gia to be a Big Sister! X-Factor Host Announces Wife Courtney Mazza Pregnant with Second Child

Mario Lopez is going to have a second child with wife Courtney Mazza. The couple broke the news Tuesday on Extra along with their two-year-old daughter Gia.

Lopez revealed the news while his daughter Gia held up a sign that read, "I'm going to be a big sister!" Lopez went on to tell Extra:

"I am the happiest father in the world.  We cannot wait to welcome Baby Lopez No. 2 into our lives."

There is no word yet if the baby will be a boy or girl. The couple is slowly trying to explain to Gia about her new sister or brother. Lopez told Us Weekly:

"We're trying to explain it to her, so now she points at Courtney's belly and says, 'Baby baby.'"

Lopez continued, "Once mama really starts popping out I think she'll understand more... I can't wait to expand the Lopez family!"

Mazza and Lopez recently got married in December at a friends house in Mexico. The wedding featured Eva Longoria as a bridesmaid. Now, just months into their marriage, the happy couple already is onto their second child. The couple has been together since Fall of 2008 where they met on Broadway.

Mazza recently spoke to US Magazine about the pregnancy and how she was feeling:

"I'm in that stage where I can't fit into my regular clothes anymore but I can't fit into maternity clothes yet either. But I'm good, it's all good!"

Lopez was married once before to actress Ali Landry in 2004. However, the marriage was quickly annulled. Lopez is well known for his time on Saved With the Bell. Along with hosting X-Factor, Lopez also is a host on Extra.

Lopez was recently asked back to become the sole host of X-Factor. Khloe Kardashian previously co-hosted with Lopez, but she was not asked back.
