Former "Bachelorette" DeAnna Pappas Stagliano and husband Stephen Stagliano are expecting their first child.

The leading lady of season 4 tweeted last night that, "I'm overwhelmed with love and joy tonight. Thank you all for making an old gal feel special! We can't wait to welcome # BabyStag."

She also added that she's 17 weeks along. In fact, her Twitter page got taken over by congrats messages from past "Bachelor" and "Bachelorette" stars like Sean Lowe and Ali Fedotowsky.

Pappas Stagliano tried to respond to as many well wishes as possible and even told one lucky person her due date was Feb. 8, 2014.

With her husband's birthday on Feb. 4, looks like he's getting the best birthday gift of all. Congrats DeAnna and Stephen!
