Cam Gigandet had an extra special Memorial Day!

In a heartfelt Instagram post on Monday, the actor’s fiancée, actress Dominique Geisendorff, announced that the couple are expecting their third child.

“So thankful for the troops out there that protect this little (expanding) family of mine,” the mom-to-be captioned a series of ultrasounds, complete with the hashtags “beyond grateful” and “#notgratefulforthegnarlymorningsickness.”

Gigandet, 32, and Geisendorff, 30, are already parents to two children, 6-year-old daughter Everleigh Ray and 2-year-old son Rekker Radley.

The former Twilight actor has also starred on Reckless and will next appear in Broken Vows.
