Rumor has it that Mariah Carey's diva ways are becoming more outrageous. Queen Mariah is said to have a personal assistant who holds and serves her drinks for her.

British TV host and comedian, Graham Norton, who recently interviewed the singer, has revealed the star, known for her outrageous demands, ordered a staff member to her side whenever she was thirsty.

Mariah Carey is to write and record mobile phone ringtones exclusively for Pepsi. The Grammy Award-winning singer has signed a lucrative deal to come up with tones for the Pepsi Cool Tones & Motorola Phones promotion.

The promotion is the first to offer music fans original tunes for their phones by some of the biggest names in the music industry.

Chris Martin stunned fans by singing an impromptu tribute - to Mariah Carey's boobs.

The Coldplay frontman made up the song after a US reporter asked him if he thought the curvy diva was "on his tail" in the race to have 2005's best-selling album.

Following the footsteps of her rival, Jennifer Lopez, songstress Mariah Carey is to launch her own jewelry line, Glamorized by Mariah Carey.

In a posting on her Web site, the butterfly singer says: "Hey Girls, I am so excited to share with you my new jewelry and accessory line," she wrote. "Wear it and you'll be a Hot Tamale."

Despite making a disastrous big screen debut in 2001's "Glitter" songbird Mariah Carey is set to take another stab at Hollywood stardom. She is to star in a new independent drama called, "Tennessee."

Variety reports the film tells the story of a waitress (Carey) who sets off with her two brothers - one of whom has leukemia - to find their estranged father.

To add to the category of "stars are weird," rumor has it that songbird Mariah Carey insists on having popcorn in her dressing room before she performs.

Popcorn seems like the last thing you'd want stuck in your throat before you perform, but again, stars are weird.
