The plunging white top showed off a great deal of her cleavage with the top of her black bra peeking out of the top.

Teamed with a tight black leather jacket, sunglasses and jeans, the star flashed her dazzling smile as she was escorted through the crowds.

Yesterday,  the star put on an even more revealing display – teaming her see-through off-the-shoulder number with tight fitting black trousers and towering platform heels.

However, there was no sign of her dancer ex-boyfriend Bryan Tanaka – amid rumours the pair have recently reunited.

It was reported the couple had split back in April with  Mariah calling time on her romance with the 34-year-old.

But last month, the couple snuggled up together in a cosy selfie during a trip to Napa Valley in Northern California.

Meanwhile, Mariah paid tribute to her late father in a cute Instagram of herself and children Moroccan and Monroe, six.

She wrote: “In loving memory of my father, Alfred Roy Carey. Happy Father’s Day, everyone. #SunflowersForAlfredRoy #HappyFathersDay.”
