“I’m going to be the grandmother from hell because I am going to spoil this baby so bad,” she said. “My son and Lisa are going to be like, ‘Get her out of here!’”

The new grandmother took to Twitter yesterday, announcing the experience of becoming a first time grandma. She Tweeted, “Today I witnessed my first grandchild being born, life changing experience. She is an angel.”
