The pair, who haven't confirmed that they are dating, coordinated their outfits to match, wearing all black along with his and hers trainers -- which are actually Yeezy Boost 350s, part of the footwear line designed by Kanye West.
The 17-year-old Keeping Up With the Kardashians star and the 25-year-old rapper were at LAX to catch a flight to Paris, according to E!
While checking through security, Kylie posted a pic of the cute matching shoes to Instagram with the caption, "Necessities."
While Kylie hasn't confirmed or denied rumors that she's dating Tyga, she did recently clear up speculation that she's had breast implants.
Responding to the claims, Kylie posted a video to Snapchat in which she said, "To whoever thinks I had breast implants, there's a whole lot of tape in here, holding these up," before flashing a portion of her taped-up chest.
Earlier this month, Kylie posted a photo to Snapchat that showed her wearing Tyga's boxer-briefs. Check out the video below for more on the controversial Snapchat pics.
