Beyonce pays tribute to Jay-Z on new single

Beyonce Knowles can no longer keep her romance with Jay-Z under wraps - she's cooing about the rapper in Destiny's Child's new single.

The sexy singer doesn't mention her man by name in the song Soldier, but it's clear she's talking about her 'secret' boyfriend, while joining bandmates Kelly Rowland and Michelle Williams in crooning about their love lives.

Williams says: "If you don't know what we're talking about, then something is wrong."

Rowland, who is engaged to American football star Roy Williams adds: "Soldier is basically talking about what you want is a soldier that is going to stand up for you. A man that is just about it.

"We actually really get into detail about the kind of men that we like, whether he's from the East Coast or the West Coast or the South side with gold grills."
