ABC/Byron CohenJon Pardi and Lauren Alaina are teaming up to play ABC's Celebrity Family Feud this Sunday.

The two country stars will try to guess what the “survey says” as they square off against actress Brooklyn Decker and tennis player Andy Roddick on the popular game show, hosted by comedian Steve Harvey.

Jon and Lauren compete to raise money for St. Jude Children’s Research Hospital in Memphis. The non-profit founded by Hollywood legend Danny Thomas works to end childhood cancer, and is completely free, with no family ever getting a bill.

You can tune in to watch Celebrity Family Feud Sunday at 8 p.m. ET on ABC. Olympic skaters Tara Lipinski and Johnny Weir face off during the other half of the show.
