Matching outfits, it must be serious! Kim Kardashian and Kanye West step out in his 'n' hers monochrome

It's getting hard to believe, as her sister Khloe contends, that Kim Kardashian's relationship with Kanye West is not serious. 

For tonight the pair stepped out wearing the kind of coordinated couple's outfit that you'd only expect to see when a couple are well established. 

Kim,31, donned an eye-catching black and white dress (which should've looked better than it did but strangely didn't work) while Kanye linked into this with a sweater in matching colours. 

His 'n' hers: Kim Kardashian and Kanye West stepped out again tonight, this time wearing complementary monochrome outfits 

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

He led her protectively along the street as they headed to a dinner in Manhattan together. 

Last night the College Dropout star joined the entire Kardashian clan for a high-profile event. 

Kanye 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.

It's there in black and white: Kim and Kanye seem to have been dating for years, but in reality they have just come out as a couple 

Just take my hand: Kanye turns to help Kim climb onto the sidewalk 

The new guard: Kendall and Kylie Jenner rocked their slightly funkier outfits as they stepped out with the family 

All the girls together (well, almost): Kendall, Kylie, Kim and front Kourtney with Mason 

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.

Appearing on US show Watch What Happens Live, she said: '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.

Brothers in arms: Rob Kardashian and Scott Disick were along for the ride, of course 

We are family: Earlier in the day Kim rocked these neon heels as she left the Gansevoort Hotel with Kourtney and Mason 

'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.'

Kim married basketball star Kris Humphries last August but filed for divorce after just 72-days of marriage, and Khloe admits she didn’t have such a soft spot for the NBA star, who she says 'rubbed her the wrong way.'

She previously explained: 'When I met Kris the very first time, I had just landed in New York and it was late at night.

Dapper little fellow: Mason looked handsome in a fitted jacket and baker boy cap for his stroll with mommy and Aunty Kim 

'One of the first things that came out of his mouth - like within the first five minutes - was, "So, how much you getting paid to fake your marriage? Like how long are you gonna keep this up for?" And I was like, "Okay, dude, I don't know if you're trying to make me laugh ..." But he just rubbed me the wrong way. 

'So ever since then I had a very defensive wall brought up. I'm a very good judge of character, if I do say so myself.'

Earlier today Kim jetted back into New York after attending an event in Los Angeles last night.

She had flew into California for a few hours to attend the Jeep brand and USA Basketball announced partnership, which named the Jeep Wrangler the official vehicle of USA Basketball.
