Miley Cyrus skips Grammys to play 'Guitar Hero'

The twerking at Sunday's Grammys was courtesy of Beyonce.

And Robin Thicke performed with Chicago.

So where, you might wonder, was his VMAs twerking other half, Miley Cyrus?

At home. "Video of tonights performance," she posted on Instagram. Yes, that's her playing Guitar Hero.

So there.

Was she missed? Depends on whom you ask.

Lena Dunham tweeted: "Missing Miley and that's no joke"

Responded Judd Apatow: " I didn't miss her. Chicago filled her shorts very well."
