AceShowbiz - Meghan Trainor and Daryl Sabara have a new addition to their family. Having welcomed their second child together, The "Better When I'm Dancin' " singer and the "Spy Kids" actor introduced the "big boy" to the world.

On Tuesday, July 4, the 29-year-old and her spouse shared photos of the two cradling their new bundle of joy. They captioned the post by writing, "On July 1st (our 7 year anniversary of our first date) we welcomed Barry Bruce Trainor into the world."

"He was a big boy at 8lbs 7oz...and sideways (transverse), but we had an amazing, successful c-section, and I finally got my skin to skin time!" the message further read. "Thank you to all of the incredible doctors and nurses who took such great care of us."

Meghan and Daryl went public with her pregnancy in April. During an appearance on "The Kelly Clarkson Show", the host initially summoned the "voice of God" to break the news but she and the couple ultimately decided to let their son Riley break the news. They shared a video of the toddler, who, following a countdown, proudly shouted, "It's a boy!"

Meghan also shared the news on "The View" and admitted she "really thought" she was pregnant with twin girls. She said, "Oh yes, I have a baby in me. It's a boy. I'm in a house full of boys. I really thought I was having twin girls, but it's a boy. I live with my two brothers, so it's a house of boys, that's what we're doing."

And though the "All About That Bass" songstress knows boys love their moms, she admitted she's second best to her husband at the moment. She laughed, "Except my oldest kid right now, two years old, 20 years old. He's in a daddy phase. I'm like, 'When's this going to end?' "
