The 'Smile' hitmaker has enlisted the services of Ted Lavender - who calls himself Ted at the Controls ' to provide the entertainment at her reception following her nuptials to fiance Sam Cooper on Saturday (11.06.11) in Gloucestershire, South West England, after hearing his demo tape - and he cannot wait to play at the event.
He told The Sun newspaper: "I do a lot of practising in my bedroom and I don't get nervous, except at the beginning.
"But mostly it's just really exciting when the crowd gets going. Lily's really nice and I'm looking forward to really rocking her party."
Ted's dad Andy revealed Lily is keen for Ted to mix reggae and ska tunes for her 150 guests to dance to.
He said: "My eldest daughter Sarah is Lily's half-sister and we're all going to the wedding. Lily wanted Ted to play.
"I've got quite a large vinyl collection and Ted really enjoys playing my records.
"He saved up to buy his own decks and spends every hour he can on them."
But Ted ' who is also set to play in the Hipshaker tent at the Isle of Wight Festival this weekend ' is not planning to be a full-time DJ.
He added: "I want to be an antiques dealer and I'll probably do DJing at the weekends."
Lily and Sam are set to celebrate their wedding with a honeymoon at Glastonbury Festival in a luxury £1,000 tepee.
