With her Napa Valley wedding to Scott Stuber just months away, has Molly Sims turned into a bridezilla?

"It's an entire wedding filled with celebrities. It's the wedding of the century," Sims, 38, joked to E! News Wednesday. "They are all celebrities, and they are all singing!"

Kidding aside, the jewelry designer said celebrity wedding planners Yifat Oren and Stephanie Cove are hard at work creating her fairytale ceremony.

"Yifat Oren and Stephanie Cove are the single best wedding planners in the United States," Sims said. "Hands down. They're whole mantra is like, perfectly messed up. It's amazing."

Sims and Stuber are certainly in good hands: Oren and Cove planned Reese Witherspoon's April wedding to Jim Toth, in addition to Charlie Sheen and Brooke Mueller's 2008 nuptials.
