Congratulations, Chelsea Houska and Cole DeBoer!
We also finally have an up-close look at the bundle of joy, and cannot get over how adorable he is.
Chelsea and Cole wed in October 2016 after being engaged for nearly one year, and they revealed in July that they had a baby on the way. While her original due date was Valentine's Day, both Cole and Chelsea's father, Randy Houska, predicted he would arrive early.
The MTV star recently hinted at her new addition's moniker, saying it would be a last name that could be used as a first name.
Fans were quick to share their guesses, but no one was able to figure out "Watson."
We bet Chelsea's seven-year-old daughter, Aubree [from her relationship with Adam Lind], is thrilled about being a sibling again!
