Kilcher, who also previously served as a judge and host on Nashville Star, initially attempted to keep her pregnancy under wraps after she discovered she was expecting on her first day of work for Platinum Hit.

Kilcher and Murray, who previously starred on CMT's Ty Murray's Celebrity Bull Riding Challenge and competed on Dancing with the Stars' eighth season, got married in 2008 after a 10-year relationship.
