Are Kourtney Kardashian and Scott Disick back on?

The exes spent the weekend vacationing together -- without their three children -- in Cabo San Lucas, Mexico, a move that's raising eyebrows and fueling reports speculating that they could be reconciling more than a year after Kourt, 37, called it quits with Lord Disick amid one of his many cheating and drug scandals.

On Nov. 12, Kourtney, who wore a revealing, colorful leopard-print bikini, and 33-year-old Scott, who donned blue and pink patterned board shorts, were photographed swimming and playing with a soccer ball in Mexico, reported both TMZ and (both outlets have photos).

Though they certainly appear close in the snapshots, they were not photographed being physically affectionate.

The trip came after both visited Rob Kardashian and Black Chyna's new baby girl, Dream, in a Los Angeles hospital following her birth on Nov. 10.

Kourtney and Scott split in the summer of 2015 after nine rollercoaster, on-and-off years together. They share kids Mason, 6, Penelope, 4, and Reign, 23 months.

In September, Khloe Kardashian speculated in a "Keeping Up With the Kardashians" teaser that Kourtney and Scott were "totally getting back together one day."

Around the same time, Kourtney told her mother, Kris Jenner, "There's so much work that would be involved and I'm so not even there yet."

Perhaps she's there now?

Just last week, Kourtney was linked to 23-year-old boxer and male model Younes Bendjima, whom she reportedly met during Paris Fashion Week earlier this fall.

She also famously stepped out with Justin Bieber following her split with Scott, who's been linked to several models and younger women over the last year.

Kourtney was also by Scott's side minus the kids in May when he celebrated his 33rd birthday with a party at 1OAK Las Vegas at The Mirage Hotel And Casino.
