Mariah Carey won't be on US X Factor!

Mariah Carey won’t be a judge on X Factor USA  despite rumors to the contrary.

Essence.com says X Factor boss Simon Cowell approached the pop diva, but she politely declined the offer, as she is busy preparing for the arrival of her twins with husband Nick Cannon and writing music for a new album.

Recent reports claimed Carey has converted an entire wing of her home into a nursery.

“Mariah and Nick have converted a whole wing of their Beverly Hills house into a luxury nursery,” a source said.

“Mariah wanted 18-carat gold trim with ivory walls, soft furnishings and walk-in wardrobes full of Petit Tresor designer clothes.

“There’s a top-of-the-range sound system and they’ll each have diamond-encrusted iPods and a flatscreen TV that comes down from the ceiling.”

Among the items the couple have splashed out on for their son and daughter are Chelsea sleigh cribs costing $2,200 each and a Clara changing table, which has a price tag of $2800, while the nursery will also be furnished with $2,270 Glam Glider chairs for Mariah and Nick and a $1 million sofa.

“Mariah and her designer Kenneth Bordewick are overseeing every detail,” the source added.

“There’s a $1 million red-crushed velvet, 24-carat gold and onyx sofa used for Michael Jackson’s shows. It’s very Alice in Wonderland with swags on the back.

“It might seem over the top, but Mariah has waited a long time for her baby dreams to come true and she says the twins will be the most spoiled kids on the planet.”
