While walking around the luxury store, the former couple looked cheery and seemed to be in good spirits. At one point, Scott even had his arm around Kourtney's left shoulder.
This wasn't the first time the two have been spotted together this week. On Thursday, Kourtney and Scott joined together for Thanksgiving dinner with the entire Kardashian-Jenner crew and their extended family. Kourtney took to Instagram to share an adorable snap with her and Scott's youngest child, Reign, who celebrated his first Thanksgiving.
A few days earlier, the duo sparked reconciliation rumors when they were spotted having lunch together, without their children, at Marmalade Cafe in Calabasas, California.
An eyewitness told ET that during their outing, Kourtney, 36, was "laughing and smiling" and seemed "happy and a little shy," while Scott, 32, appeared "confident and comfortable" and "was a gentleman towards Kourtney."
While they have yet to confirm if they are officially a couple again, both Kourtney and Scott have been open about staying close for their three kids following their most recent split in July, after Scott was spotted with another ex-girlfriend in Monte Carlo. In addition to their boys, Mason and Reign, Scott and Kourtney are also parents to 3-year-old daughter, Penelope.
Despite their recent outings together, their post-split relationship drama is being played out on the current season of Keeping Up With the Kardashians. In the latest episode of the reality TV show, Kourtney accused Scott of partying too hard and frequently flaking on their children.
