The couple, who wed in February 2011, attended the 2014 Vanity Fair Oscar Party in West Hollywood on Sunday, March 2. Kayte hid her burgeoning baby bump under a little black dress. An insider tells Us that Grammer was spotted rubbing her belly during the night.
The spouses are already parents to daughter Faith, 19 months. The birth of their first child together was bittersweet. They had initially announced they were expecting twins, but tragically lost their baby boy. The couple said in a statement to Us at the time: "It was unspeakably painful and we know that people will understand our desire to keep the news private then, as we know they will respect our privacy in this matter now."
Grammer is already dad to Spencer, 30, Greer, 22, Mason, 12, and Jude, 9, from previous relationships. He is also a grandfather to Spencer's son Emmett, 2.
During an interview with Access Hollywood Live back in August 2012, Grammer revealed that he'd like to have even more children with wife Kayte. "I think we'll have at least two more, if not three or four," he said at the time. "I think it's a great way to live a life."
