Reality star Kim Kardashian has reportedly set a strict dress code for her upcoming nuptials -- she has asked her guests to wear only black or white, with no exceptions.

This suggest the star will buck the trend of a traditional white gown when she walks down the aisle to marry Kris Humphries on August 20, said a wedding guest Kathie Lee Gifford.

'Kim knows better than anyone how to stay dramatic and there is no way she would let herself blend in with everyone else at her wedding by wearing a white dress,' News.com.au quoted Gifford as telling The Huffington Post.

'If I know her, I bet she will wear red or some colour so she pops against everyone else who will be in black or white,' she stated.

While it has been widely reported that Kardashian will be dressed in Vera Wang, all other details of the designer gown have been kept closely under wraps.

Beyonce Knowles has revealed that she thinks she can now 'dedicate' herself to having children, after having worked hard as a teenager and now that she is nearing 30.

According to InStyle magazine, the 29-year-old R and B recording artist, who had previously hinted that she wanted to have children with husband Jay-Z, made it clear that as a teenager it was the right time to work hard and make her career, and can 'focus' on her relation with the 41-year-old rapper now that she is approaching 30.

'When you're young --18 or 19 -- you have the energy and drive. That's the time to work as hard as you can,' Contactmusic quoted her as saying.

'Now I'm a woman, and because I gave it my all, I can focus on my marriage. I can decide I want to have kids. I can be the mother I want to be and dedicate myself to my children,' she added.
