A couple of weeks ago Beyoncé revealed exclusively to us what she bought at the Pat Field store, after "Page Six" reported that she spent $11,000 there in one trip. Since her attention span for blogging was only so long, she could only reveal a scant portion of her purchases. But on Saturday at Hans Dorsinville's birthday party, Patricia Field herself confirmed to us that Beyoncé's purchases included a handmade mask. Pat had no idea what it was for, but we hope Beyoncé's contemplating the alter ego she'll halfheartedly embrace when her Sasha Warrior phase ends. Raven Firestorm perhaps?
