Justin Timberlake's grandmother is planning his wedding. Although Justin hasn't proposed to girlfriend Jessica Biel yet, his gran Sadie Bomar has already chosen a venue for the couple to get married.

Sadie - taking an apparent swipe at Justin's ex, Cameron Diaz - said: "I just want them to be happy. Justin should get married in his mother Lynne's back yard in Tennessee. She has a big yard with beautiful flowers. I think it would be perfect. "Jessica's really sweet.

She's his age and isn't possessive. I think their personalities are a lot alike." A friend of Justin - who has been dating the 'I Now Pronounce You Chuck and Larry' actress since last January - says he has talked about marriage, but admits he has no idea that his family are already planning his future for him.

The source added to Britain's The Sun newspaper: "Justin started talking about marriage earlier this year. His family were delighted and started planning his big day. I'm not sure how much he knows about it." In June, Justin was seen shopping for an engagement ring and had reportedly asked Jessica's close friends to help him choose the perfect diamond band.
