Twilight's Cam Gigandet is prepping for another round of diaper duty!

Already dad to 3-year-old daughter Everleigh, Gigandet, 29, is expecting his second child with fiancee Dominique Geisendorff, JustJared confirms.

News of Gigandet and Geisendorff's pregnancy comes on the heels of other Hollywood baby news. Over the July 4th holiday, Us confirmed that both Matthew McConaughey's wife, Camila, and Claire Danes are also expecting.

Gigandet -- who appeared as Kevin Volchok on Fox's The O.C. and starred in Twilight -- will soon be seen in Free Ride, opposite mom-to-be Anna Paquin, later this year.
