The stork has officially paid Chris Klein and his wife, Laina Rose Thyfault, a visit.

The couple have welcomed their first child together, a son, born on July 23.

They named their bouncing baby boy Frederick Easton Klein.

"So incredibly blessed and forever grateful for my amazing wife & our healthy baby boy. Laina delivered me a miracle," Chris captioned a photo of his sleeping son on his WhoSay account on Wednesday.

His wife couldn't stop gushing about the duo's first child either.

"So excited to announce our precious baby boy, Frederick Easton Klein was born 7/23/16. This little Champ has already mastered his warrior pose and is doing great," she said while posting another snap of their son. "Our hearts are bursting with love and joy #staylittleforever #wakingupklein #chrisklein #partyofthree."

The "American Pie" star's rep told Us Weekly, "All is well! Mother and baby are home and doing wonderful. Chris is so in love. The baby was born healthy and two weeks late in the couple's hometown of Austin, Texas."

Chris and Laina got engaged in December 2014 after dating for three years. In August 2015, they married in Montana.

The couple announced that they were expecting on Facebook in May.

"My beautiful wife Laina and I are expecting our first child. 23 weeks along," Chris wrote, alongside a picture of his wife's belly. "Gratefully blessed on my 37th B-Day."

The couple had been counting down the days until the birth, often sharing their journey with fans on social media.

"Feeling as ready as can be! Can't wait to snuggle this kid," she said in mid-July. "Chris is hoping to watch #theopen with our little love bug this weekend but it's looking doubtful at this point. We probably went overboard because we have five different sleeping devices throughout the house, guess we will see which ones get used and which ones end up in storage! #40weeks6days #40weekspregnant #countingdowntobabyklein #theopen #snugglenest."

Chris posted a photo cradling his wife's belly around the same time, thanking the photographer for "capturing my beautiful wife and I before this kiddo comes to shake things up."
