Though it originally appeared that the tennis great had taken sides in Brooklyn Decker and Andy Roddick’s showdown on the series, Williams pulled a fast one, appearing in each of the stars’ final performances. In a teaser clip from the Thursday episode shared earlier this week, Decker, 31, had Williams, 37, join her onstage for her performance of Beyoncé‘s hit track, “Sorry.” Decker danced in front of a bus that Williams stood atop of in a black leotard and over-the-knee boots, with Roddick appearing visibly shocked and excited to see his wife had help from the athlete.
