Jamie Lynn Sigler pregnant Cutter Dykstra jeans cartigan tee shirt ball player Guys With Kids

Aww, they're so cute together!

But still, we were wondering why these two got engaged so quickly, and after the news broke yesterday that Jamie-Lynn Sigler and fiance Cutter Dykstra were expecting their first child together, it all started to make sense.

While a shotgun wedding isn't such a big deal these days, we were surprised that the 31-year-old actress and the 23-year-old minor league baseball player got soooo serious soooo quickly.

Today we snapped them grabbing lunch at Toast in West Hollywood, and while the former Sopranos starlet was a bit moody, she did flash us a smile and a peek at her barely-there baby bump.

The parents-to-be announced their engagement via Twitter on January 28.
