Arie, 37, took to Instagram to make the happy announcement and give an update on his little family.
"We have a healthy, BEAUTIFUL baby girl 6lbs, 13oz 20cm long. Mommy and baby are doing great, we are so incredibly happy," Arie posted on his Instagram stories.
The new parents have yet to release their daughter's name or first photo.
"I think, to be honest, in the beginning we were both hoping that we were having a girl. I have a little brother, and he’s so sweet and I love him to death, but sometimes I don’t really understand why he acts that way he does. I’m feeling a lot more confident in being able to be a girl mom first!" Lauren told Us Weekly back in January.
The two wed in Hawaii in January 2019 and took a babymoon in the Bahamas a couple months later in April.
