Update: Sources confirm that Nick Cannon and Mariah Carey celebrated their wedding Tuesday night at Six Flags Magic Mountain in Valencia, Calif. Only 100 of their closest friends, family and business associates were invited, including Mariah's manager, Benny Medina, Nick's father, and his half-brother, Reuben.

Still no word of a honeymoon, but newlyweds Mariah Carey and Nick Cannon are planning a big blowout tonight.

A source tells E! News that the two lovebirds are renting all of Six Flags Magic Mountain theme park for a private party.

All the roller coasters you can ride until you throw up...sounds romantic! Guess these two really are "eternally 12 years old" after all.

And this is just one stop on their busy schedule: Last Saturday, they were at Ellen DeGeneres' 50th birthday bash and then hit Villa on Monday night for some drinks and dancing.

Coming up, Nick's jet-setting back to New York City to deejay at the Stoli Hotel soiree Friday.

No word on whether Mimi will join her man that night, but the way they've been attached at the hip lately, it wouldn't surprise us.
