Mariah Carey is uncharacteristically casual in black trousers and plunging white shirt as she spends day on the beach with her twins Moroccan and Monroe

She's been making the most of the summer sun in recent months, after having gone on an extended holiday in Europe with her new boyfriend James Packer. But Mariah Carey made it strictly family time only as she stepped out on Malibu beach on Wednesday with her adorable twins, Moroccan and Monroe. The 45-year-old singing superstar cut an unusually casual figure as she walked across the beach with her two little ones, who splashed about in the water.
