Lewis Hamilton worried about Nicole Scherzinger`s weight loss

London: Lewis Hamilton is worried about singer and ex-girlfriend Nicole Scherzinger`s weight loss and wants her to take care of her health.

The duo recently ended their seven-year-long relationship, but they are still in touch. "Lewis has seen the recent photos of Nicole looking stick-thin and is really concerned," dailystar.co.uk quoted a source as saying. However, Scherzinger thinks differently. "He told her `enough is enough now`. But Nicole actually likes her new, skinnier figure. She thinks it`s great," said a source.
