If the rumors are true, it looks like Kendall Jenner won't be forgetting 5 Seconds of Summer's name any time soon.

Jenner, 18, ignited rumors that she and 5SOS drummer Ashton Irwin had something goin' on after they were spotted getting into a cab together on Monday night (August 4) in New York City. Fans caught the two leaving in the taxi together and quickly snapped pics -- and some even included their own commentary:

Of course, 5SOS are currently supporting One Direction on their Where We Are tour, which could prove just a little awkward for Jenner, considering she used to date Harry Styles. And we all felt that secondhand embarrassment when she accidentally introduced the Aussie band as One Direction at the 2014 Billboard Music Awards.

To fuel the dating rumors even more, Jenner and her pals took a selfie with Ashton and his bandmate Calum Hood earlier that day, in an Instagram snap that Jenner's friend Nicole Kahlani posted on the photo-sharing app. (You can check out that photo below.)

Both 5 Seconds of Summer and One Direction were in town on Monday and Tuesday, performing two shows in a row at MetLife Stadium in New Jersey.
