That's not Lady Gaga. It's a woman forty years her senior. Seemingly there's no age limit to streaking onstage. Yaaaaaay. We're not sure whether to applaud or stuff our eyes full of gauze.

This is Cher performing at her gig in Boston during the week, where she also appeared to ape Beyonce...

Then she actually turned back time to to 1989. There is no rear view shot, something her son is probably thankful for.

 These are just a few of the ten outfit changes she made onstage. This is by far our favourite.
