Beaming Mariah Carey puts on a busty display in low-cut top as she rocks the double-denim trend  

Mariah Carey has made some questionable fashion statements over the years but she showed no sign of giving up her experimental streak as she stepped out in California on Monday.

The chart-topping singer was a vision of nineties style as she was pictured sampling the double-denim trend while strutting out of Mastro's Restaurant.

Mariah, 45, put on a busty display as she squeezed her ample cleavage into a low-cut plain black top.

The We Belong Together hit-maker teamed the vest with a pair of straight-leg jeans and a cropped denim jacket which flattered her curvaceous form.

She added a touch of glamour to the otherwise casual look with a pair of black criss-cross heeled sandals.

Mariah - who is dating billionaire businessman James Packer - let her natural blonde hair, which was styled in tight curls, flow free down her shoulders.

She made sure to uphold her famed diva status by donning a pair of large sunglasses to presumably protect her eyes from the paps' flashbulbs.

Although her attempt to go incognito failed to some degree, she didn't let that dampen her spirits and appeared to be in a good mood.

Mariah beamed from ear-to-ear as she made her way home from the eatery, accompanied by members of her entourage.

Mariah has plenty to smile about as she is to be honoured with her own star on the Hollywood Walk of Fame later this week.

Understandably, she can hardly contain her excitement and took to Twitter on Monday to inform her followers of the ceremony details.

'Can't wait to see my #Iambs #Iambily Wednesday for my Hollywood Walk of Fame star ceremony!,' she tweeted.
