Rebecca Gayheart, three months pregnant, is having a rough time with morning sickness, sources say. The actress is expecting her first baby with husband Eric Dane of “Grey’s Anatomy.” But she’s not having an easy time and was spotted at an OB-GYN office in LA earlier this week. A spy said, “She was complaining of severe morning sickness.” The couple, who have made no secret of their desire for a baby, hope this will be a new start for them after the scandal over their nude home video. Gayheart’s rep declined to comment.
