Kim Kardashian and Kanye West step out in his 'n' hers monochrome

London, Apr 25 (ANI): Kim Kardashian and Kanye West stepped out wearing a kind of coordinated couple's outfit as they headed to dinner in Manhattan together.

While the 31-year-old socialite donned an eye-catching black and white dress, West into this with a sweater in matching colours.

It certainly made the fledgling couple look in sync, though the 34-year-old rapper found his loafers easier to walk in than the TV reality star did in her obligatory Louboutin heels.

He led her protectively along the street as they headed to dinner.

Even though Kim's sister Khloe insists that the relationship is not serious, the College Dropout star joined the entire Kardashian clan on Tuesday evening.

He accompanied the whole family to the opening of Kourtney's boyfriend Scott Disick's restaurant where their every affectionate moment could be captured by the cameras.

The couple arrived together holding hands, their first public declaration that they are in a relationship together.

The action was to say the least a rather large sign that the singer is moving ahead with his relationship with the curvy star.

And it was no wonder he wanted to rush to his ladylove's side.

Kim stepped out for the event looking elegant in a black tight-fitting pencil skirt and matching halterneck top with frill detailing at the bib.

She paired the look with some black satin and perspex pointy stilettos, a black weave clutch and two gold cuffs on each of wrists.

Her boyfriend of a matter of two weeks appeared to be matching his outfit to his girlfriend's.

The 'Touch The Sky' rapper looked dashing in a black tuxedo-style suit with a simple grey T-shirt worn underneath.

Khloe - who with husband Lamar Odom enjoyed a double-date with the fledgling couple in New York last weekend - revealed things between her older sibling and the Gold Digger rapper are only just getting off the ground.

"I don't think it's serious. I think it's too soon. But because they've been friends for so long, it''s just so easy and that's something I love seeing for Kim - the easiness and how happy she is. And it's just more of a great friendship and friendships make the best relationships," the Daily Mail quoted Khloe as saying on 'Watch What Happens Live'.

"We've known Kanye for like nine years. He's great with the family, but again we've known him for so long. It's not like some stranger getting into a hurricane," she added. (ANI)
