Katy Perry was in Hollywood, California, last night for the 2012 ASCAP Pop Awards, held at the Hollywood Renaissance Hotel.

The singer, who’s still sporting a much more flattering purple do, wore a Temperley London Spring 2012 gown.

Her sheer ivory gown is beautiful with its intricate embroidered details, so I’m not quite sure why she’s channelling her inner Courtney Love by wearing one of the straps off the shoulder.

You would notice…right? Especially when you are as well endowed as Katy, but in every picture the strap sits on her arm, which has the potential to turn into a major wardrobe malfunction.

Cleary still in a boho-hippie mode from the Coachella Music Festival, Katy accessorized with a daisy accent headband.

A beautiful rouge lip colour completed her look.
