Already working on their wedding plans, Jamie Cullum and Sophie Dahl reportedly are eying to get married next July. The twosome, who got engaged in March this year, is expected to exchange vows at Hunton Park estate, a mansion set in 22 acres of parkland in Hertfordshire, the Daily Mail reports.

"It is a really beautiful estate and they have earmarked it as the venue. The couple have a few more to look at, but Sophie loves it," reveals a source. "They are looking at hiring Bentleys for the wedding party and having a full silver service reception with all the trimmings."

"They have the option of marrying in either a marquee that can accommodate 170 guests or having an evening reception with a maximum of 250 guests," adds the source. Another source, meanwhile, claims that Sophie has been organizing her wedding details with the help from her mother Tessa. The mother-daughter duo "are now working amicably alongside each other to create the perfect wedding," states the source.

Jamie Cullum and Sophie Dahl have previously defended their height difference. The model told The Times Luxx magazine, "We happen to be two people who met, fell madly in love and will probably produce fairly average-sized children, hopefully with his more elegant feet, not mine."

Professionally, Jamie is working on his new album "The Pursuit", which is expected to be released later this November. It is the set that forced him and Sophie to postpone their wedding from January to July next year.
