Justin Timberlake oversaw all details of his wedding to Jessica Biel.

The 31-year-old singer took charge of organising the big day in Italy and with the help of his mother Lynn Harless, picked out all the flowers and food in order to make Jessica's big day perfect.

A source told Life and Style magazine: ''Justin obsessed over the details even more than the bride-to-be. He and his mother oversaw the flowers, the food, the cake.

''[Justin and Jessica] arranged for a chapel to be specially built in the Borgo Egnazia resort.''

Justin wanted everything to be perfect for his new wife as after five years together he knows she is the one for him.

The insider said: ''Justin proposed to Jessica because he really loves her and knows that she is the best woman he's ever going to get.''

Lynn is equally delighted with her new daughter-in-law and it was her blessing that pushed Justin to propose last Christmas.

The source said: ''Justin's mom loves Jessica and thinks she is incredible and wonderful.''
