It will be the first child for the actress.

It's a been a whirlwind of a year for Keshia. On New Year's Day, she tied the knot with her husband, former NFL player Ed Hartwell, much to the surprise of her family and friends.

On the podcast, Keshia said she surprised their families with the wedding. "It was my dream. We did it literally in our living room in our home," she said. "We come from large family. I'm one of four, Ed is one of six. We invited people. They had no clue they were coming to a wedding. They thought they were coming to a New Year's party."

The couple announced their were engaged just the previous night, on New Year's Eve, when Keshia shared a snap of her with her new diamond sparkler.

"Happy to spend not only my new year but my life with this guy!!!," he captioned a shot of them kissing.

Earlier that week she gushed about her then-boyfriend on social media. "I fell in love with his heart & selflessness…," she wrote on Instagram. "No where I'd rather be than enjoying a night of paying it forward with my love @edhartwell !! #Stars4Wishes #MakeAWish."

On her podcast, she spoke of how she and Ed met.

"I had known Ed in passing for years. We never really connected in that way. He was married previously, I was dating someone else...He was so not on my radar. He came actually and helped with my nonprofit and that's what opened the door. I tried my best not to like him."

This will be Ed's second child, as he shares a son with "The Real Housewives of Atlanta" star Lisa Wu, whom he was married to for almost six years.
