Anna Faris dances in granny undies after skirt flies off on Ellen

If only we could all live life like Anna Faris: carefree and, er, pants-free.

The 39-year-old star of the TV comedy Mom lost her skirt while making a grand entrance on Ellen, revealing a pair of daggy nana knickers.

As the audience looked on in shock, Anna just kept on dancing. And this here is the meaning of life – watch above!

Of course, it was all planned. But Anna pulled off the miraculous dress disappearance to perfection, probably thanks to a wire. Ah, the magic of television.

Now we just need Anna's husband, Jurassic World's Chris Pratt, to whip off his pants on TV and we'll be happy.

Head to 9Jumpin for Ellen and Mom catch-up.
