Bethenny Frankel Reveals That She Was Paris Hilton and Nicky Hilton's Childhood Nanny

The former "Real Housewives of NYC" used to drive Paris Hilton to school.

"I've known Kyle [Richards] for years," Frankel said of the actress. "I used to work for Kathy Hilton and take Paris and Nicky to school and so I knew them through Kyle, who's a friend of mine and she was coming into town so I got together with her in the Hamptons."

Richards has previously acknowledged her longtime friendship with Frankel, 44, posting a "flashback Friday" picture of the two "Real Housewives" stars posing together.
