Me and my big mouth...?

I work with a woman named Angela she's about 22 and she works in the same room as me at the Daycare (the newborns room). Angela is single and inherited an incredible amount of money from her father so working at the Daycare is only because she loves it. Angela is a good person and I like to consider us good friends. She tells me all about her life, but she doesn't tell anyone else. Anywho I slipped a few details about her money stance to this worker Melanie. I think I said something like, "She's blessed to be set for life". Then Melanie told everyone else and they started being hateful to her because they resent her. Then the big trouble came. Angela found out that at the Daycare you can bring in your child for free and they can stay with you in your room. Her daughter Hayley is gorgeous...a head full of black hair, huge blue eyes with long eyelashes, big lips, and chubby cheeks and she dresses her in the cutest clothes. Now everyone treats her worse. What should I do?
