Watch Scotty McCreery's Grandma Flirt With Steve Harvey on 'Celebrity Family Feud': Exclusive

Scotty McCreery may be the star in his family, but when it came to appearing on Celebrity Family Feud,  the country chart-topper took a backseat to his grandmother, Paquita, who steals the show.

McCreery and four members of his family take on Saturday Night Live alum Chris Kattan and his family Sunday night on the ABC game show, as the two teams compete to win cash for their favorite charities. McCreery’s family is playing for St. Jude Children’s Research Hospital; Kattan’s for Partners in Health.

Paquita shamelessly flirts with host Steve Harvey, making sure he knows she's single, before trying to answer the question on reasons why a date would end early.

Watch below as McCreery’s grandmother cracks up the singer and the whole panel, and catch the full show Sunday night at 8 p.m. ET on ABC.
