After the New England Patriots defeated the Falcons 34-28, Witherspoon shared a tweet congratulating Patriots quarterback Tom Brady on his record fifth Super Bowl win.
"What. A. Game," she tweeted. "Y'all kept me on the edge of my seat Good work @AtlantaFalcons! Congrats, #TomBrady! #SB51 #Overtime."
The mother of three's 17-year-old daughter, Ava, didn’t seem to be present for the festivities, but Witherspoon recently revealed a hilarious case of mistaken identity involving her eldest.
"I had a premiere for that movie Sing! over Christmas, and the head of the studio went up to Ava and congratulated her on the movie," the 40-year-old actress gushed to ET’s Nischelle Turner last month, at the Elle’s Women in Television event in West Hollywood. "But I just love her. I’m so lucky to be her mom."
