Grammys 2013: Katy Perry’s Hot Date Is Girls Star Allison Williams!

Katy Perry‘s mint green Gucci gown was the talk of the Grammys 2013 red carpet last night, almost leaving her hot date Allison Williams in the shadows. 

Katy chose to take her BFF, Girls star Allison, along to the bash, leaving her boyfriend John Mayer to walk the red carpet on his own. Ouch! 

All eyes were on KP’s amazing floor-sweeping gown which featured a gorgeous embellished neckline and PLENTY of cleavage. The likes of Elton John, Ellen DeGeneres and Portia De Rossi were spotted eyeing up Miss Perry’s assets, while Ryan Secrest was left breathless by the star during their short interview.

Talking to the E! News presenter about her hairstyle, Katy said: “I was inspired by Priscilla Presley in the ’70s. The big hair, closer to God.” 

Allison, who plays Marnie in HBO Drama Girls, wore a stunning Kaufman Franco dress with Stephen Webster jewels.  

She said last week: “She’s the hottest date. She’s a friend of mine and she’s nominated, as she should be. I can’t wait to go. Obviously she’s awesome. She’s the best.”  Judging by the intimate snaps of John cosying up to Katy during the ceremony, it’s clear he thinks so too!
