Kylie Jenner and Tyga are fueling romance rumors once again. The pair were seen strolling through LAX as they boarded a plane to Europe together.

The 17-year-old “Keeping Up With the Kardashians” star and 25-year-old YMCMB artist were spotted preparing for take off wearing matching outfits -- black pants and tops with Kanye West’s latest Adidas creation, the Yeezy Boosts 350. Kylie shared a photo of her brother-in-law’s handiwork sitting in bins waiting to be scanned by TSA agents. She captioned the photo, “Necessities,” but did not tag Tyga. Kylie and the “Rack City” rapper made their way through the international terminal before boarding a plane to France.

The rumored couple were reportedly headed to Cannes Lions, the largest award show and festival for creative communications professionals in the world. Upon arrival they apparently planned to meet up with the rest of the Kardashian clan. Kim Kardashian shared a tweet confirming that her teenage sister, as well as mom Kris Jenner, were in France for the big event.

Kylie and Tyga have been linked since he ended his engagement to Blac Chyna with whom he shares a 2-year-old son. Both have tried to deny that they are anything more than friends, but that has done little to quell the rumors. Their might-be romance has been surrounded by much controversy due to the fact that Kylie is still under the legal age of consent in California. She has gone on record as saying she is "single," even saying so during a November 2014 episode of her family's hit reality show.

Tyga did the same in February 2015, telling Power 105.1’s “The Breakfast Club” he “didn’t leave my family to be with Kylie,” adding that those stories were “ridiculous.” Unfortunately it seems Kanye didn’t get the “deny, deny, deny” memo. That same month he appeared on the show where he told hosts Charlamagne Tha God, Angela Yee and DJ Envy he thought Tyga “was smart” to have gotten with Kylie at such a young age.
