The cast of Bryan Singer's X-Men: Apocalypse dropped by Conan O'Brien's show, which is filming at San Diego Comic-Con, and Olivia Munn described how she squeezes into her Psylocke costume.

The 34-year-old actress had her cast mates and even the redheaded talk show host blushing as she explained the process she goes through to put on her X-Men costume. She says it involves two women applying copious amounts of lube to her body so she can fit into her tight superhero suit that is made of latex.

Listen to Munn explain it in the video clip below.
