My gf is pregnant. her belly button was pierced & now that skin flap is tearing as her belly grows. any ideas how to sooth or stop this tearing?

Belly Piercings: Have you removed the piercing? If not it may be time to do so.

Take out the ring: Take our the ring and use lot of lotion for now.

Massage?: Usually the skin will stretch as the uterus grows, since it grows so slowly (it may not seem like it is slow to you, but it is). If it is tearing anyway, a light massage may help stretch the scar and allow it to stretch more without tearing (stop if it hurts). This would have to be done several times a day for a few minutes at a time. Sometimes it can look torn, but just be a stretch mark instead.
