Nicole Sullivan is in the beginning of season two of Rita Rocks, but there are already major changes in the storyline.

Rita is pregnant - and that’s because the actress was carrying her second child during production.

Sullivan survived all those fun elements associated with pregnancy, including morning sickness and fatigue, but it was all worth it.  Not only does she have a new son, but Sullivan was able to celebrate working moms everywhere with Rita’s on-screen life.

Sullivan also tells HollywoodOutbreak.com that she takes nothing for granted by getting another season.  But, she understands that had Rita Rocks been on the major networks, the show would probably not have gotten the time to develop a following.

Rita Rocks airs, Tuesday, 10:30 p.m. ET/PT on Lifetime.
