Beyoncé and Jay-Z Break the Internet With Olympian Costumes The Carters continue to keep the pressure on. Their couples costume took home the gold and honored two influential athletes. Bey dressed as track star, Florence Griffith Joyner. Jay-Z dressed as Tommie Smith. A track star who broke records in the 1968 summer Olympics. The Beehive couldn’t get enough and took to Twitter. @StephBMore, via Twitter @fivefifths, via Twitter @MatthewACherry, via Twitter Beyoncé also channeled R&B singer, Toni Braxton, and became “Phoni Braxton” this Halloween. The costume was so spot on that Braxton praised Queen Bey herself. Toni Braxton, via Instagram Toni Braxton, via Instagram
