Us Weekly broke news in October that the Mad Men actress, 34, was expecting her first child with the musician, who's also Canadian. Paré was the guest of honor at an L.A. baby shower in February.

"Jessica was super lovely and gracious and genuinely appreciative of the party," an insider told Us at the time. "She got to spend time just socializing and was glad to be spending time with her friends and family!"

Famous guests in attendance included Mad Men costar January Jones, show creator Matt Weiner, and executive producer Scott Hornbacher.
