Adele will reportedly marry in a '50s-themed ceremony in July.

The British singer and her fiancé Simon Konecki welcomed their son - believed to be called Angelo - into the world in October last year. They have been beset by rumours they tied the knot in secret, but have laughed them off.

It's now been claimed the couple are finalising wedding details, with their special day taking place at the end of July.

They reportedly want the day to have a '50s theme, although the fine details remain a secret.

"It's been one of the best years of Adele's life and to get married is the most amazing way to round it off. She's never been so in love," an insider told Heat magazine.

Although Adele has enjoyed a stellar year having won an Oscar for her James Bond song Skyfall, she isn't planning to flash her celebrity on her big day. Instead she wants to keep things laidback and relaxed.

"She's planning a modest do at a local church in a small village near their home in Sussex," the source added. "The reception will just be at their house - it's all very low-key. Even the menu won't be fussy - Adele likes good home-cooked food."

It was recently claimed the 24-year-old star has already picked her wedding dress designer, with Jenny Packham making the cut. The fashion house's spokesperson wouldn't comment on the speculation, although Jenny is known to be one of Adele's go-to red carpet designers.

The star is apparently planning to branch out from her usual style for the union.

"She's joked around, but she won't be wearing a black dress on her wedding day - though she's not sure it will be white either," the source explained.
