Britain's Prince William and fiancee Kate Middleton pose for photographers after announcing their engagement in November.

Planning a wedding is a full-time job -- even more so when it's a royal ceremony expected to be viewed by billions around the world. So it's understandable that Kate Middleton formally gave up her job with her parents' party supply company, Party Pieces, on Friday, to devote her full attention to the nuptials now only 13 weeks away, according to Britain’s Daily Mail newspaper.

"We have always said that she will be starting to wind down her responsibilities in the family business as the wedding draws closer," a spokesman for the royals told the Windsor Knot. "It is not like she suddenly quit. Kate is now concentrating on preparing to become a member of the royal family."

Kate has worked with her family as a project manager, photographer and website designer since leaving her job at fashion retailer Jigsaw, where she was employed from 2006 to 2007. She currently lives with Prince William in Anglesey, Wales, near the RAF base where he is stationed as a search and rescue helicopter pilot, and where the two plan to remain after they tie the knot.

"After the wedding Kate will entertain royal engagements first and foremost with Prince William," said the spokesman. "With time, she will likely take on patronages of charities close to her heart."

Kate and William are said to be intimately involved in planning every detail of the April 29 wedding. And while the main details of the big day have become public knowledge, Kate and Wills are keeping their lips tightly sealed when it comes to the tidbits that the public really want to know, like the wedding dress designer and the location of the honeymoon.

The wedding ring designer may be one detail that Kate will decide on in the next few weeks. Goldcrest Jewellers in Dorset told BBC News that they received a letter from the prince's office confirming that they are in the running to design the royal rings. Several months ago, the firm offered their services to the royal family.

Here’s a quick roundup of some of the details we do know:

• The wedding will take place at 11 a.m. on April 29 at Westminster Abbey.
• Kate will travel to the Abbey by car, and will likely spend her last night as a commoner at the Goring Hotel, the Daily News reported.
• The Archbishop of Canterbury Rowan Williams will marry Prince William and Middleton, and the Dean of Westminster will conduct the service.
• Queen Elizabeth will hold a large reception after the ceremony at Buckingham Palace. Later in the evening, Prince Charles will host a more intimate party for friends and family at the palace.
