Prince Charles has offered Lily Allen advice on what to do when she's feeling fed up, reports the Daily Star.

The Prince met the 22-year-old singer at the premiere of The Other Boleyn Girl and advised her to get a Japanese Peace Flower to talk to whenever she's feeling down.

Allen ignored the Prince's horticultural advice for the time being to spend a night out with her actress friend Jaime Winstone.

Allen's younger brother Alfie, who replaced Daniel Radcliffe in the play Equus, is currently dating Jaime, daughter of Hollywood actor Ray Winstone.
