Popsugar Celebrity Oscars Timothée Chalamet With Matthew McConaughey at 2018 Oscars Timothée Chalamet, King of Third-Wheeling, Poses With Matthew McConaughey and Camila Alves at the Oscars 5 March 2018 by Kelsie Gibson Image Source: Getty / Kevin Mazur Timothée Chalamet has been adorably third-wheeling with costar Armie Hammer and his wife, Elizabeth Chambers, all award season long, but he decided to switch things up for the Oscars. On Sunday, the Call Me By Your Name star, who is nominated for best actor, looked too cute for words when he posed alongside his former Interstellar costar, Matthew McConaughey, and his wife Camila Alves. Not only did Timothée match the model in his white tux, but he also shared a sweet moment as he laughed with Matthew in front of the cameras. Perhaps they were laughing over Timothée's spot-on impression of the Oscar winner.
