London, Feb 21 (IANS) Singer Mariah Carey and her husband Nick Cannon have reportedly converted an entire wing in their Beverly Hills home into a nursery for their unborn twins.

The couple is sparing no expense in making the babies’ surroundings as comfortable as possible.

‘Mariah and Nick have converted a whole wing of their Beverly Hills house into a luxury nursery,’ femalefirst.co.uk quoted a source as saying.

‘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 has splashed out on are Chelsea sleigh cribs costing $2,200 each and a Clara changing table, which has a price tag of $2,800. 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. 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,’ the source added.

‘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.’
