On Friday night, it was clear that the 34-year-old and partner Scott Disick are still very much in love after two children and seven years together as they headed to a dinner date at their favourite restaurant.
The pair enjoyed a romantic bite at Sugarfish in Calabasas, California - the same day Kourtney's sister Khloe filed for divorce from husband Lamar Odom.

Strong as ever, Kourtney and her 30-year-old beau walked arm and arm as they headed back to their car after the date.
Obviously knowing the father of her two children - Mason, 4, and Penelope, 18 months - loves every part of her, Kourtney skipped her makeup routine.
While the Keeping Up With The Kardashians star clearly put effort into choosing an outfit she did not feel the need to doll up, as besides going au natural, she also just threw her hair up into a haphazard bun.

For date night, the reality star wore a pair of cropped leather pants with a two-toned black and grey fur jacket and patent pointed toe stilettos.
Taking a note form his partner's style book, Scott also shunned colour, donning a causal ensemble of black pants, a long sleeved white top and a pair of black leather loafers.
The couple were enjoying a little them time ahead of a day of celebration for their oldest, Mason, who turned four on Saturday.

Posting a picture of her young son on Instagram, Kourtney wrote: 'Happy Birthday to my precious angel who has forever blessed my life. The happiness this boy brings me has no words to describe it.'
Mason's birthday was no doubt a welcome distraction for the Kardashians who have been on a rough relationship trot recently.
On Friday, Kourtney's younger sister Khloe filed for divorce after four years of marriage to basketballer Lamar.
Earlier this year, mother Kris Jenner and step father Bruce also separated after more than 20 years of marriage.
