On stage, Liza handles Oprah's question about marrying her fourth husband with humor. "Liza kind of handled it," Sheri says. "She didn't answer directly but I think you could read between the lines." 

When the time comes for Liza's performance, the 64-year-old stage veteran cements her legendary status. "She was great, hit every note perfectly," Bridgette says. "I love her even more now that I met her."
