First things first; why, Matt Bellamy does indeed appear to have a new muse (apologies). Her name is Elle Evans, in case you were wondering. You may recognise her from that Blurred Lines video She's no Nick Jonas, but she does seem lovely. 

As for the rest of the style on display, it was the usual eclectic mix - from the flowing gowns adorning Gwyneth Paltrow, Diane Kruger, and Jaime King...

 

To the Hollywood Glam from Lea Michele...

Sarah Hyland embraced the autumn in the air with a very dark berry lip...

While Sharon Stone and Zendaya Coleman brought a more androgynous edge to proceedings... the latter's been taking style tips from Pharrell

Rosie Huntington-Whitely broke against the norm for her, and sported an understated black number (avec the all-important pockets)...

While Emma Roberts and Chloe Sevigny's dresses had a bit more going on...

And then there was the bum note. Here it is from the front, courtesy of Violet Chachki.

And then she turned around. How's that for some spectacular bum cleavage at its best. If you scroll down, it could actually be a bodice yer looking at.
