Miley caresses her own crotch and also points to Robin's with her foam giant hand prop

Miley Cyrus put on a startling performance at the MTV VMAs 2013 last night.

Liam Hemsworth‘s 20-year-old fiancée started off dancing with teddy bears in a tight leotard for We Can’t Stop but stripped down to nude latex underwear to gyrate with Blurred Lines star Robin Thicke.

Robin, in a bold black and white striped suit, looked rather self-conscious as Miley twerked away in an embarrassing crotch-grabbing routine which was almost pornographic.

Miley even bent down and wiggled her bottom at Robin in a very raunchy gesture and pointed to his manhood with a large foam hand prop.

‘Today’s already the f***ing best day ever! Just wait till VMAs tonight,Miley Tweeted earlier in the day.

Well, she seemed to be having a good time.
