Pippa Middleton hoped Adele will be her wedding singer

Pippa Middleton and James Matthews got engaged on 17 July.

Pippa Middleton was allegedly hoping to hire Adele to sing at her wedding. It was recently revealed that the 33-year-old English socialite and Kate Middleton's sister is engaged to her boyfriend James Matthews.

According to Us Weekly, the Duchess of Cambridge's sibling wanted the Hello singer to perform at her nuptials. However, she later called off that plan because Adele was too costly for her.

A source said: "Pippa realized how expensive she'd be!"

Pippa has reportedly "been really hands-on" when it comes to wedding planning.

"Pippa doesn't want it to be too expensive or look gaudy," the insider added.

Pippa and the 41-year-old hedge-fund manager got engaged on 17 July during a vacation to England's Lake District. She is extremely happy over her engagement to Matthews.

A source told E! News: "They've always had sizzling chemistry. He's now 40 and ready to settle down. She's over the moon as she definitely didn't expect an engagement so soon! While there is talk the wedding could be next year, Pippa has always been keen that her own nuptials are very different to her sister's."
