The actress, who portrayed the lovable but sometimes vain MTV mama, is expecting her second child. Nikki is already mama to three-year-old son Hudson; Jenna Hamilton and baby Morgan are the offspring of the "Carefrontation" letter-giver.
"Only my @hallmarkchannel family could get this very pregnant lady out for a night on the red carpet," Nikki captioned the photograph above on Instagram. While the glowing soon-to-be mother of two didn't reveal any more details about her bun in the oven, the announcement post garnered some likes from some fellow Palos Hills folks (aka Molly Tarlov, Jillian Rose Reed and Barret Swatek).
