Kardashian’s older brother sent rumors when Kim shared a sweet photo of her and Scott, 37, as he lovingly wrapped his arms around their son Mason, 10.
And in a second set of snaps, Kourtney captured an adorable moment as she and Scott set out for mountain biking.
The former couple were seen beaming with stunning views of the coast behind them as they took a selfie together.
Scott then turned the camera around, showing his ex riding a bike next to him as they enjoyed a day trip together.
Reversing the rumor, Kourtney posted the photos to her Instagram and played it shyly teasing fans with the caption: “Selfie selfie.”
Fans flocked to the post, which racked up over a million likes in less than an hour.
The footage raised hopes that she had rekindled her romance with Scott after calling for an end to it nearly five years ago.
Scott and Kourtney, who share children Mason, 11, Penelope, seven, and Reign, five, have sparked new speculation they’ve rekindled their romance after Lord Disick split from longtime girlfriend Sofia Richie.
But despite their separation, they remained close friends and devoted co-parents.
Rumors of romance come as sister Kim came under heavy criticism this week when she flew 30 of her closest family and friends to a remote island aboard a private jet to celebrate her anniversary.
She would have lost $ 1 million by taking them all for the lavish break.
Kim has come under fire for her lavish getaway after revealing her loved ones had to face two weeks of quarantine and medical screenings so they could join her on an island paradise.
Piers Morgan is among those who criticized her, calling her a “deaf fool”.
Page Six reports that Kim spent $ 1 million leasing a private 88-seat Boeing 777 jet to transport her and her loved ones to the island of Tahiti.
Kim was joined by a number of her friends and family, including sisters Kourtney, Khloe and Kendall, brother Rob, and mom Kris Jenner.
Kris’ handsome Corey Gamble was also there, as was ex-Khloe, Tristan Thompson.
