Cornet started her year by playing for France at the Hopman Cup. She won all three of her Group-B singles matches, beating Heather Watson of Great Britain (6–2, 6–2), Casey Dellacqua of Australia (4–6, 7–5, 6–1), and Agnieszka Radwańska of Poland (6–4, 2–6, 7–5). Due to Jo-Wilfried Tsonga withdrawing from the Hopman Cup because of an arm injury, Cornet's mixed-doubles partner was Benoît Paire. They beat the Polish team Agnieszka Radwańska/Jerzy Janowicz (4–6 ret.) and the Australian team Casey Dellacqua/Marinko Matosevic (7–6, 7–5), but lost to the British duo Heather Watson/Andy Murray (4–6, 6–2, [8–10]). France did not qualify for the final as they finished Group B only in third position. At the Premier tournament in Sydney, Cornet lost in the first round to third seed Radwańska in straight sets.
