Katy Perry Accidentally Appoints Lindsay Lohan Her Maid Of Honor

Kooky crooner Katy Perry got a tough lesson in holding her tongue while holding her liquor after she drunkenly requested that Lindsay Lohan be the maid of honor at her upcoming wedding to comedian Russell Brand.

Katy spent last weekend partying at the Coachella Music Festival in Indio, California — sans Russell, who has been busy completing stand-up shows. Lindsay was also at the event, and the two women quickly became friends, bonding over beer and the sounds of Beyonce dueting with hubby Jay-Z. Disaster ensued when Katy joked that Lindsay should help her plan her wedding — a request the actress apparently took quite seriously.

A spywitnesses dished to Britain’s Daily Star Tuesday: “Both the girls were having a right laugh, talking about Katy’s wedding and their plans over summer. At one point Katy joked that Lindsay would be her perfect maid of honor. Katy was in high spirits and obviously just messing around. But before she knew it Lindsay was telling everyone she couldn’t wait to be part of the ceremony and as maid of honour it was her job to sort out the hen night. Katy didn’t know what to say or where to look. It started to get embarrassing for everyone. She obviously didn’t mean it as a serious invitation.”

Earlier this month, pop star Rihanna told media personality Ryan Seacrest that she would be in charge of planning Katy’s bachelorette party.

Katy and Russell will reportedly wed in India or Tokyo in December 2010.
