Jennifer Lopez is turning grey. The Latino beauty's tell-tale roots were clearly visible down the centre parting of her otherwise golden locks at an awards ceremony in Los Angeles on Sunday. An onlooker said: "People could barely believe their eyes. She looked stunning in every other way but everyone was distracted by the inch-thick grey-white root."

J.Lo, who is due to turn 37 in June, was accompanied to the 2006 NCLP Alma awards - which recognises Latin performers and was hosted by Desperate Housewives star Eva Longoria - by her husband Marc Antony.

The Maid in Manhattan actress is usually the talk of the red carpet because of her famously curvy backside, but on this occasion the groomed star let her perfect image slip.

The onlooker added: "Considering it was one of the biggest events in the Latino calendar, you'd have thought she would have found time for a trip to the hairdressers and a quick re-tint."
