Singer Adele, expecting her first baby with boyfriend Simon Konecki, has spent $54,000 on sound and lights for her baby's nurseries and $7,500 on clothes and accessories.

"Adele might have a reputation for being a bit of a spendthrift, but when it comes to her baby she's sparing no expense. She is building state-of-the-art nurseries in all her homes," contactmusic.com quoted a source as saying.

"She's having bespoke wallpaper made and it's costing a fortune with climate control and cameras so she can see everything on her laptop. She's spending $54,000 on the lighting and sound system alone," the source added.

The 24-year-old singer, due to give birth in September, has also been splurging on clothes and accessories for the baby.

"She's pre-ordered Bon Point unisex baby clothes and they don't come cheap. And she's already bought three Bugaboo pushchairs and a $900 Moses basket. Not to mention the small fortune she's spent in Tiffany's on picture frames and trinkets. She even bought an antique bear for $7,500," said the source.
