Drew Barrymore might be in her third trimester and Adam Sandler might have had to leave his celebrity fight-club meeting early (or so we assume, because damn), but they both still managed to make it to the Tonight Show Wednesday night to celebrate their third rom-com coupling in the upcoming Blended via song.
