Who’s ready for another Kardashian wedding? Kourtney Kardashian is head over heels for boyfriend Younes Bendjima — and ready to make it official with the 24-year-old model.

Kourtney, 38, and Younes’ relationship really heated up in the South of France, where they vacationed earlier this month. Now, sources are revealing exclusively to Life & Style that the KUWTK star is busy planning a fall wedding.

“She had never planned to tie the knot with anyone, but Younes changed all that,” says an insider. “Kourtney is ready to be in a healthy relationship and walk down the aisle with him.” Her ex, Scott Disick, proposed several times over the course of their decade-long relationship, but she turned him down every time.

However, things are different with Younes — who Kourtney is sure will be the perfect groom. “Younes is a hundred times more mature than her ex,” says the insider, who adds that the trilingual hunk impressed Kourt by ordering in French on a recent date. “He’d rather work out than spend all day drinking. Drinking is always at the top of Scott’s list of things to do.”

Kourtney is looking to her family to make sure the small and intimate wedding goes smoothly, asking her sisters to be her bridesmaids, and recruiting her sons Mason, 7, and Reign, 2, as ring bearers and daughter Penelope, 5, as a flower girl. And about that 14-year age difference? Kourtney is not worried. “Both Kourt and Younes are very active, plus she thinks he’ll make a great dad,” explains the insider.

Meanwhile, Scott, 34, is spiraling out of control — and friends are worried he may be headed down the wrong path. “Scott is in the worst shape he’s ever been in,” a source told Life & Style. “Friends and family fear he’s headed for an overdose.”

The source added that Scott, who is currently dating 19-year-old Bella Thorne, “can drink five days in a row with barely any sleep.” Yikes!
