Tiffani Thiessen and family

Tiffani Thiessen has been up-front about trying for baby number two, so the actress and  Dinner at Tiffani's star was understandably thrilled to announce her pregnancy last week via a cute Instagram pic (shown here) with hubby Brady Smith and 4 1/2-year-old daughter Harper Renn.

"We are excited to announce the news that we are expecting," she posted. "Harper could not be more thrilled to have a sibling and a playmate."

Now, Thiessen has shared what we think is one of the world's cutest gender reveal photos—from what looks to be the same Elizabeth Messina photo shoot—with The snap shows Smith and Thiessen, with her arm around Harper, cutting into a white-frosted ruffle cake and pulling out a...[drum roll] slice!

Congrats to the happy (adorable) family on their it's-a-boy news!
