Watch Lena Dunham and Jimmy Fallon compete in Lip Sync Battle

Lena Dunham and Jimmy Fallon competed Friday night (June 12) in a Tonight Show lip sync battle, complete with sporty Nike gear.

Dunham came prepared with a Nike skort, jacket, workout shirt, tennis shoes and hoop, heart-shaped earrings.

Fallon began the battle in his suit by lip syncing with a handheld mirror to the slow tune of Charlene's 1982 hit "I've Never Been to Me."

Dunham performed next with a lip sync to Calvin Harris and Ellie Goudling's "Outside." The Girls star channeled her inner musician by embracing the ground on her knees and stomach while mimicking the words.

For Fallon's second song, the late-night host opted for Run-D.M.C.'s "Run's House," which he completed with a dropped microphone (which he caught): "I was going to drop the mic, but it's very expensive."

Dunham asked for help from the audience for her second song, Queen's "Fat Bottomed Girls," and encouraged viewers to sing along and clap.

Dunham took home the victory title and Fallon exclaimed: "I can't beat Queen!"
