The Keeping Up With The Kardashians star was clearly feeling in a romantic mood on Tuesday (4 June) as she uploaded the black and white picture of them to her Instagram account.
Kourtney's sweet image was taken back in 2010 when the couple were together in New York.
At the time, Scott and Kourtney were about to celebrate their son Mason's first birthday.
Fast forward two and a half years and they're now also parents to daughter Penelope, born in July 2012.
Kourtney, 34, recently joined Scott in Las Vegas to celebrate his 30th birthday, calling it a night she'll "never forget".
"We seriously had the best time celebrating his day," she said last week. "We hung out at the pool with our friends and then went to see David Copperfield's magic show before dinner. Then for the big celebration we went to Hyde nightclub and danced the night away with our friends!
"Definitely a night I won't forget.
Kourtney recently helped throw a baby shower for her pregnant sister Kim. Along with sister Khloe and mum Kris Jenner, the women hosted a bash in Los Angeles on Sunday (2 June) to mark the upcoming arrival of Kim's baby girl; her first child with boyfriend Kanye West.
