Drop Dead Diva

Mariah Carey always has someone around to make sure she's looking beautiful -- proven in these pictures ... which show the rule applies even when she's hitting a theme park.

The singer was at Universal Studios' Islands of Adventure in Orlando Wednesday -- where she was celebrating her twins Moroccan and Monroe's 13th birthday ... and Mama Bear herself ended up getting on one of the rides, which sent her 'do into a frenzy.

The photos are pretty freakin' hilarious -- you can see MC hanging on for dear life as she gets whipped around on the rollercoaster ... and her long, luscious locks are flying high.

Mariah Carey siempre tiene a alguien a su alrededor para asegurarse de que se ve hermosa, y quedó demostrado en este registro que confirma que la regla se aplica incluso cuando visita un parque temático.

La cantante estuvo en Universal Studios Islands of Adventure en Orlando el miércoles -celebrando el cumpleaños número 13 de sus gemelos Moroccan y Monroe, y mamá terminó subiéndose a una de las atracciones.

Las fotos son hilarantes. Se puede ver a Mariah aferrarse a la vida mientras la montaña rusa toma velocidad... y se puede ver su cabello por los aires.

The cast and crew of "Drop Dead Diva" may be out of work after today ... but at least they'll have something fun to do while they wait for residual checks.

The show just wrapped for what could be its final season ... and sources on the set tell us the entire staff -- from the stars to the grips -- got beach cruiser bikes as parting gifts.

We're told they were all called together for a big good-bye speech thanking them for their hard work ... and then told to go outside where 115 Old Skool beach cruisers -- each with a name tag -- were waiting for someone to ride them ... we're talking the bikes.
