Kanye West can't stop smiling as wife Kim Kardashian goes braless

Surly Kanye West rarely flashes a grin in public, but little did anyone know that all it would take was for his wife to cheekily expose her ample assets to bring a smile to his dial.

On Saturday, Kim Kardashian and her 37-year-old husband enjoyed a date night out in West Hollywood, where the reality star gave onlookers more than they bargained for as she donned a see-through top without a bra.

The 33-year-old reality star dressed to impress her husband by showing off her voluptuous figure in a tight-fitting charcoal high-waisted skirt that clung to her shapely hips and bottom.

The mother-of-one chose to go without a bra under her matching sleeveless bodysuit, revealing her breasts in the process - presumably unaware of just how sheer it was.

Completing her look was the prerequisite pair of towering stilettos, the Keeping Up With The Kardashians star opting for strappy pale grey ones on this occasion.

She kept her make-up understated and natural, her eyes shielded behind a large pair of dark sunglasses, while she slicked her brunette locks back into a low ponytail with a heavy centre part.

The couple had arrived separately for their romantic dinner date and upon reuniting with his other half, the rapper couldn't contain his excitement, grinning from ear to ear like the Cheshire Cat and even giggling - which is even more out of character.

While his wife was fashion-forward as always, Kanye opted for a more casual outfit.

The rapper dressed comfortably in his favoured look of a grey T-shirt and hoodie,which he dressed up somewhat with tight black leather pants and dark brown suede boots.

The pair wore his and hers gold chains around their necks featuring the name 'Nori' in honour of their adorable 16-month-old daughter, North West.

Kim has been very open with her desire to have another baby with Kanye - and sooner than later.

And it seemed she received some very good news recently when she hired a psychic to give her a reading at the couple's home.

She told E! News at the Charlotte Tilbury make-up launch at The Grove in LA on Thursday that her psychic, Jayne Wallace, shared 'so much, so many good things' about the possibilities of a sibling for North.

When asked what baby predictions were read, Kim replied: 'That's what it was all about! It was exciting but I don't want to give it all away but she said so many good things you hope it's true!'
