Timberlake's mother opposes wedding?

Justin Timberlake's mother Lynn Harless is against his relationship with Cameron Diaz, Star magazine says this week.

The singer, 23, is planning to tie the knot with the actress, 32, later this year but his mother's apparent disapproval could call a halt to the proceedings. Timberlake has such a strong relationship with Harless that he has her initials tattooed on his back alongside the word "guardian."

"Nobody knows why she doesn't like Cameron; maybe it's because she thinks no one is good enough for her son," a source told the magazine. "It could be the age thing, too. Supposedly, she wasn't thrilled when he was dating Alyssa Milano (who was also nine years his senior)."

Just last week Timberlake's ever-talkative gran said she preferred his former flame Britney Spears over Diaz.
