Matthew McConaughey and his wife, Camila Alves, made a glamorous appearance at Variety's Unite4:Humanity benefit at the Montage Hotel in Beverly Hills on Thursday night. The pair dressed to the nines in coordinating black and white ensembles and struck their best poses for photographers on the red carpet. The annual event ho**red Matthew, along with Morgan Freeman, Olivia Wilde, Gina Rodriguez, and Seth Rogen, for their philanthropic efforts in the U.S. and abroad. Like any proud wife, Camila took to Instagram to gush about her husband, writing, "Thursday night! Ho**ring my better half on the amazing work for the @jklivinfoundation #variety #unite4good #whatsgood. @jklivinfoundation #variety #united4good."
