Mariah Carey and Nick Cannon took their marriage to new heights Tuesday evening when they, as OK! first reported, hit up L.A.'s Six Flags Magic Mountain for a private celebration.

With 100 guests, purple and pink balloons and banners emblazoned with "Nick and Mariah: A Love Story," the newlyweds enjoyed an evening full of fun and surprises. In fact, the event was a shocker to Mariah herself as her new hubby planned the get-together.

"Normally I hate surprises, but this is a smash hit!" the songstress tells Entertainment Tonight. "I love roller coasters!"

The couple, who tied the knot in the Bahamas on April 30, arrived in a Rolls-Royce around 8 p.m. and were escorted into the closed facility.
