The 55-year-old yoga instructor, who is expecting a baby girl, said she cried when she watched a birthing video recently, reported Contactmusic.
"Now I have to start thinking about giving birth. I haven't thought about that before. I saw a birthing video the other day and I cried. Hopefully I will survive. I just have to remember that a lot of people have babies, it's a unique experience and I will be okay," she said.
Thomas revealed that her husband has been very supportive during her pregnancy.
