Kim Kardashian and Kanye West enjoyed a double date on Friday night (20.09.13).

The 32-year-old reality TV star and her boyfriend of 18-months left their three-month-old daughter, North West, at home with a babysitter for a rare night out together and were spotted having dinner with rapper Tyga and his girlfriend Blac Chyna.

The quartet dined at upmarket Japanese eatery Hakkasan in Beverly Hills, according to the MailOnline website.

The 'Keeping Up with the Kardashians' star wore a tight-fitting white top and jeans but disguised her post-baby body in a large pink coat.

The brunette beauty's personal trainer Tracy Anderson recently revealed that Kim is taking a very relaxed approach to losing her pregnancy weight.

The fitness guru previously said: ''She's a gorgeous woman. I think the reason why the weight is coming off is because she's very connected. I went and met little North and Kim's really taking it in stride.''

Kim has maintained a low profile since giving birth to North and has only been spotted out a few times in public since June.

But it was recently revealed she is planning to go on tour with Kanye, 36, who is set to launch his new 'The Yeezus Tour' in the U.S. next month.
