The new mum enjoys a sophisticated evening out

Kim Kardashian stunned in a classy grey gown for a night at the opera on Friday.

The reality star showed off her curves in the fitted frock and gave a flash of cleavage as she attended the LA Opera with Kanye West.

Baby daughter North didn’t join her parents but Kim, 32, once again wore her cute Nori name necklace as a reminder of her little girl.

The new mum clearly loved her sexy dress as she had been spotting wearing it while out and about in Los Angeles earlier that day.

Meanwhile Kanye, 36, opted for a more relaxed look in a white shirt and a pair of frayed denim jeans.

The couple must have been unwinding after reportedly spending Friday morning doing a punishing workout together.

They were spotted training at Barry’s Bootcamp class at 6.30am in matching black outfits and onlookers say they put on a ‘cute’ PDA while working up a sweat.

‘It was super early and a gruelling workout,’ a source tells Us Weekly.

‘[But they were] all smiles, showing affection toward each other and being very encouraging.

‘[They were] smiling at each other in the mirror when they were running side by side on the treadmills.’
