Mariah Carey and Nick Cannon weren't kidding when they recently described themselves as "eternally 12 years old."

On Tuesday night, the newlyweds celebrated their surprising April 30 nuptials by turning Six Flags Magic Mountain -- which has one flag for each week of their head-spinning courtship -- into their personal playground.

People says the apparently deep-pocketed Cannon, 27, covertly rented out the Valencia, Calif., amusement park (a move that may have set him back six figures) as a grand gesture to wow his missus, 39.

The impulsive, diamond-encrusted pair, who incited a paparazzi riot Monday evening as they exited a Los Angeles hot spot, turned up for the informal wedding party in a Rolls-Royce around 8 p.m., according to TMZ.com.

Hey, big spender: Nick reportedly spent $2.5 million on Mariah's 17-carat pink sparkler and forked over six figures for their Six Flags festivities.

"This is wonderful," Mariah enthused as she walked into the park (per People). "The best surprise ever!"

About 100 people received an invite to the festivities, quite a crowd compared to the half-dozen pals who witnessed their seaside Bahamian vow-swap.

"Entertainment Tonight" conveniently scored a golden ticket (Cannon is buddies with correspondent Kevin Frazier) and reports the park was festooned with purple and pink balloons (Carey's signature hues) and signs emblazoned with the not-at-all cheesy sentiment, "Nick and Mariah: A Love Story."

"They were so affectionate," a guest tells People. "It was like watching two teenagers in love."

"ET" snapped the pair holding hands -- their rock-covered digits prominently displayed -- as they rode the roller coaster, an image that may eventually serve as an apt metaphor for a marriage many expect to be filled with very high highs and very low lows.

"When they got off the ride, Mariah wanted gum so Nick unwrapped a piece and fed it to her," an onlooker recounts to People. "He is head over heels."

And Mimi is just as high-maintenance as ever. After the ride, her minions quickly moved in to smooth her tresses and touch up her makeup.

OK! believes the fun-filled shindig was inspired by Ellen DeGeneres, who invited Mr. and Mrs. Cannon to her carnival-themed belated 50th birthday bash in Los Angeles last weekend.

The soiree was a big topic of conversation when the blushing, cleavage-flashing bride joined Ellen on her talk show Tuesday.

In between showering the sneaker-loving host with fuzzy, high-heeled slippers and satiny lingerie, Carey kvelled about her overconfident husband's anniversary plans.

"Instead of trying to be like, 'You're invited, but, shhh! Don't tell anybody' we're just going to have another [wedding] next year," she explained. "His plan is to have one every year."

(Incidentally, the vow renewal isn't exactly a novel idea -- Heidi Klum and Seal retie the knot annually.)

Mariah also reiterated her newfound desire to procreate, responding in the affirmative when Ellen asked about the possibility of poopie diapers.

"I always said, if I found the right person who I felt would be on the same page as me in terms of raising kids and having the same belief system, [we'd have children],'" she said. "I've always had a weird thing about it because my parents divorced when I was three and I didn't have many examples of what was the 'norm.'"

But is Mariah, who recently told OK!, "It's hard to have kids in this world. I don't think I could properly educate a child right now. Maybe in the future, but actually I haven't thought about it. For now I enjoy my dog Jack's company," already looking to stock up on haute couture onesies and baby-sized Louboutin stilettos?

The New York Daily News says one of the chart-topper's assistants contacted L.A.'s go-to baby boutique Petit Tresor to discuss ideas for a nursery.

A spy says the underling asked for fabric samples and a design concept incorporating -- no, not rainbows -- butterflies, Mariah's favorite insect (she's not only inked a butterfly tattoo on her lower back with "Mrs. Cannon" written down the middle, but the Six Flags fete also had lepidopteran touches throughout, including cupcakes topped with hand-painted butterflies).

Her aide also reportedly requested that the chichi store close down for a private meeting the next time she's in town.

But Carey's manager, Benny Medina, pooh-poohs to the paper that she's not in the family way.
