The couple, who got engaged in October after dating for about 10 months, turned up the heat with their steamy romantic display while attending family friend Simon Huck and Phil Riportella's wedding on Saturday, Nov. 13.
To celebrate the newlyweds, the Poosh founder and Blink-182 drummer dressed to impress in matching head-to-toe black ensembles.
The Keeping Up With the Kardashians alum slipped into a curve-hugging little black dress by Gucci, which featured a unique asymmetrical neck strap. As for Travis? The rock star looked suave as ever wearing a classic tuxedo.
"Going to the chapel," Kourtney captioned her Instagram on Saturday evening, with her fiancé cheekily responding, "Our turn next [red rose emoji]."
Both Kourtney and Travis shared behind-the-scenes clips of their friend's lavish wedding, which included personalized menus that had drawings of their faces.
At one point, the pair also shared an intimate moment during the reception, which was captured by guest Claudia Oshry—who is known as Girl With No Job online.
Taking to Instagram Stories, Claudia captured footage of Kourtney straddling Travis, as his band Blink-182's hit single "All the Small Things" played in the background, with guests singing along enthusiastically.
And while the duo plans to get hitched, a source recently told E! News they are making plans to start a family together.
The insider explained that they are "hoping to be expecting by next year."
Another source echoed similar sentiments, adding, "They would love nothing more than to have a baby together. Kourtney has always wanted another baby and never felt like she was done. Now that she's with Travis, she wants it even more."
Kourtney is already a mom to kids Mason, 11, Penelope, 9, and Reign, 6, who she shares with ex Scott Disick. Travis also shares 18-year-old son Landon and 15-year-old daughter Alabama with his ex-wife Shanna Moakler.
