Congratulations are in order for Twilight hunk Cam Gigandet!

The 32-year-old actor and his fiancée, Dominique Geisendorff, 30, are expecting baby No. 3!

The actress announced the happy news by posting an ultrasound shot on Instagram yesterday, May 25 (which just so happened to be Memorial Day).

She captioned the pic, “So thankful for the troops out there that protect this little (expanding) family of mine… #BeyondGrateful #NotGratefulForTheGnarlyMorningSickness.”

The O.C. actor and his wife-to-be are parents to six-year-old daughter Everleigh and two-year-old son Rekker.

Congrats to the entire (expanding) family on the exciting news!
