Kathy Hilton has a bone to pick with her new son-in-law Carter Reum.

Paris Hilton and her mother dropped by “The Tonight Show” to chat with Jimmy Fallon about life advice for audience members.

Paris went on to explain her mother coined the nickname “because he’s got his mitts into everything” as he was so busy – a trait that came up during the wedding planning for the couple.
