"Rihanna's professional, works hard and stays away from drugs and alcohol, but Jay wants her to be careful," Look quotes a source as saying. "He told her to take a holiday for a week - she's been working flat out and needs to get over the bronchitis, which he's sure she's developed as a result of stress. He told her she'll be alright, but to keep her head down," added the source.
