08:46 AM ET 05.11 | In advance of Mother's Day on Sunday, Robert Griffin III's mom, Jackie, sat down for a chat with FoxDC to reveal some things about her son. For instance, she called him Robbie when he was a child. Also, his older sister used to dress him up as a baby doll. Perhaps the biggest piece of information was that, according to Fox reporter Shawn Yancy, RGIII and his fian'e, Rebecca Liddicoat, are getting married this summer. The wedding news has been kept secret until now, and Jackie said that's typical of her son.
