"We have a BEAUTIFUL baby girl," he wrote in an Instagram story. "Mommy and baby are doing great, we are so incredibly happy."
The couple's daughter, whose named was not revealed, weighed in at 6 lbs 13 oz.
Luyendyk and Burnham met while filming season 22 of "The Bachelor."

The couple announced their pregnancy back in November.
