Chelsea, who is set to welcome her first child with fiancé Cole DeBoer, was more than happy to chat with fans about the announcement on Twitter earlier today, and told MTV News: "We’re really excited and Aubree is pumped to be a big sister."

The reality star, whose first delivery was featured on season 2 of 16 and Pregnant, admitted that she's feeling a little more apprehensive the second time around, saying: "I feel more nervous for some reason! It's been a while and I want to do everything perfect."
 

When asked whether she and Cole had planned to have a child before their wedding, Chelsea responded: "Not unplanned! But happened faster than we expected! Super happy! We are very lucky."

"Sometimes it's scary sharing such personal things and letting so many people/opinions into our lives," Chelsea told her 1.5 million followers today. "You guys have made us feel so amazing."

Thanking her followers for their support in light of the announcement, the reality star tweeted: "So overwhelmed by all the sweet comments and support. You guys have no idea how much it means to us."

Chelsea and Cole got engaged in November 2015 after a year of dating.
