Justin TimberlakeJustin Timberlake has reportedly bought a $50,000 necklace for girlfriend Jessica Biel on Madonna’s recommendation.

A source told the Sun: “Working [together] on her album meant Justin hasn’t spent much time with Jessica lately and Madonna didn’t want to be the cause of problems between them.”

“She suggested he buy her a gift, something expensive.”

Justin is said to have bought the I Now Pronounce You Chuck and Larry star a white gold and emerald chain from exclusive jeweller H Stern and presented her the gift at her home in Los Angeles recently.

A source close to the couple added: “Jessica loved it - both the necklace and the gesture. Things are going well between them.”
