Mariah Carey has converted an entire wing of her home into a nursery.
The singer is currently pregnant with twins and she and husband Nick Cannon are sparing no expense in making the babies' surroundings as comfortable as possible.
A source said: "Mariah and Nick have converted a whole wing of their Beverly Hills house into a luxury nursery.
"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.
The source added to Now magazine: "Mariah and her designer Kenneth Bordewick are overseeing every detail.
"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 spoilt kids on the planet."
