Timberlake gave Biel four wedding rings

Jessica Biel received multiple wedding rings from Justin Timberlake.

The newlywed 'Hitchcock' actress - who tied the knot with the 'Love Stoned' singer in a lavish four-day bash in southern Italy earlier this month - helped design four stackable wedding bands to go with her enormous 18-carat engagement ring.

The 31-year-old singer told People magazine he collaborated directly with Leor Yerushalmi of The Jewelers of Las Vegas to create the very "personal" white gold and black rhodium plated engagement ring - which also features two aquamarine elements representing Jessica's birthstone - and the couple were eager to have equally special wedding rings.

They worked with the designer for several months to create their complimentary rings.

Justin opted for a simple yellow-gold domed ring with a hammer finish, while his 30-year-old bride chose four stackable weddings bands, two of which are the same as Justin's ring and the other two are said to be white gold with a black rhodium finish and covered in diamonds.

Jessica is said to have worn only one of her wedding bands during their ceremony on their special day at the Borgo Egnazia resort in Puglia, Southern Italy on October 19.

The actress also decided to accessorise her beautiful Giambattista Valli haute couture pink gown with yellow pear-shape diamond drop earrings, set in 18-carat rose gold and micro-set with 96 fancy pink diamonds, from jeweler Martin Katz.
