Country star Jake Owen and his girlfriend are expecting first child together

Nicole "Snooki" Polizzi isn't the only one who made a Thanksgiving Day announcement that there's a baby on the way.

On Thursday, country star Jake Owen surprised everyone when he revealed on TV that he and his girlfriend Erica Hartlein are expecting their first child together.

"This'll throw you guys for a loop," Owen told his family during Thursday's episode of an "I'm Coming Home" special on ABC. "(We) haven't told anyone, but Erica and I will be having a little addition to our Owen family."

Owen's family, including his fraternal twin brother Jarrod, went crazy with excitement as they congratulated the expecting couple.

"Now I'm gonna turn really red!" Hartlein said as she smiled at their reactions.

"I hope it's twins!" said Owen's mom.

Don't clip your child's wings. Your toddler's mission in life is to gain independence. So when she's developmentally capable of putting her toys away, clearing her plate from the table, and dressing herself, let her. Giving a child responsibility is good for her self-esteem (and your sanity!).

"Gotta have a little boy!" his dad said.

Thanks for the birthday wishes. Getting older is a blessing. I’m thankful to live this life and to be given the greatest gift I could ever receive. Not a bad way to wake up on my birthday. Happy Birthday to my twin bro Jarrod too... love and miss ya bro

The baby will be Hartlein's first child and Owen's second. Owen was previously married to model Lacey Buchanan and the couple have a 6-year-old daughter together, named Olive Pearl.

Owen frequently posts photos on social media of his daughter, who prefers to go by her middle name. In August, he shared a particularly sweet photo of Pearl sleeping on his chest.

"Not a bad way to wake up on my birthday," he captioned the photo.

During the summer, the doting father took his daughter on a fishing excursion. When Pearl said she didn't think she could put bait on a hook correctly, Owen encouraged her and said, "yeah, you can." And she did it!

Heidi Klum (mom of four: Leni, Henry, Johan and Lou (above)): “I’m not someone who [lives] like, ‘OK, this is a museum and you can’t sit here and you can’t touch this and everything has to be put in its place - [the kids] live here as much as we do. You come into our house and a giant elephant and lion are welcoming you. We have toys and things everywhere.”

Owen also posted several photos of Pearl at the beach throughout the summer. "My little hippie chick," he captioned a photo of Pearl wearing big sunglasses that look as if they may have belonged to her dad.

"My most beautiful part of my life. My Pearl," he wrote under another photo of Pearl at the beach, painting coconuts on a tarp and smiling.

With a new baby on the way, it seems that another beautiful piece is going to be added to his life.
