Lena Does 'SNL'
Getting naked and other things Lena Dunham did on 'Saturday Night Live.'
We all know that Lena Dunham has a thing for dancing (see here and here), so her surprise Late Night with Seth Meyers appearance should not surprise anyone.

On Monday, the 28-year-old donned a platinum blonde wig, an all-white outfit and danced the night music segment away — for Sia.

The performance — for Sia’s hit “Chandelier” — involved some lip syncing, poster board punching, making a mess with a roll of toilet paper, spooning with Sia (who performed face down on a bunk bed) and of course, a whole lotta dancing.

Watch the epic routine, above.

Girls will return to HBO for a fourth season in early 2015.
