Cam Gigandet is a dad -- again! The Twilight actor and his fiancee, Dominique Geisendorff, welcomed their second child, a baby boy, on Jan. 23, according to a post on his official Facebook page.

"Dominique gave birth to our second child, son Rekker Radley Gigandet, on 1/23/2013," the 30-year-old star wrote on Facebook on Jan. 29. "He is healthy, happy, and perfect."

"We are humbled to have the opportunity to call ourselves the parents of this beautiful soul, and I am forever grateful to God for allowing me to know this kind of boundless, immaculate love," the proud papa continued. "Thanks to those of you who wish to send your positive energy and well wishes."

Gigandet -- who appeared as Kevin Volchok on Fox's The O.C. and as Christina Aguilera's love interest in Burlesque -- has been engaged to Geisendorff since 2008. The couple are already parents to daughter Everleigh, 3.
