LOS ANGELES, California (X17online) - Kim, Khloe and Kourtney arrived in a Cinderella-like horse-drawn carriage to the opening of Famous Cupcakes in Beverly Hills last night.

And apparently, we weren't the only ones to think this arrival was way over the top - the girls got stopped by the cops on the way to the bakery!

"Getting pulled over while riding in the horse & carriage while on our way 2 @FamousCupcakes event!!!" Kim tweeted from the carriage.

But the cops didn't dampen the girl's spirits. A photog on the scene says, "I've never seen the sisters look so happy. With Khloe's wedding, Kourtney's baby, and now Kim back with Reggie, it seems like they truly were the Cinderellas of the night, who have finally gotten everything they wanted!"

Dressed in mini-dresses, the girls showed that all their hard work keeping fit paid off...in cupcakes!
