Harry Styles' ex-girlfriend Kendall Jenner has sparked dating rumors with a member of One Direction's current support act for "Where We Are" tour -- 5 Seconds of Summer's Ashton Irwin.

After the 1D concert at the MetLife Stadium in New Jersey on Monday, Aug. 4, a photo of the 18-year-old reality star getting into a taxi with the Australian drummer circulated on Twitter.

The couple then headed to the Mercer Hotel to hang out with Irwin's bandmate Calum Hood, model BFF Hailey Baldwin, and twins Nicole and Danielle Kahlani, who do hair and makeup for 5SOS. Nicole posted a snapshot of them, writing the following caption: "R&B moment."

According to The Mirror, the "Keeping Up with the Kardashians" reality star is now more interested in the "Amnesia" singer than her former flame Styles. "Kendall and Harry have been over for quite some time. They were dating at the start of the year but it fizzled out so she has absolutely no ties to him," a source revealed. "She's perfectly entitled to party with the 5 Seconds of Summer boys without him, so she and her friend Hailey went along to visit them in their hotel as they have mutual friends."

"She and Ashton seemed to really hit it off, though they were also hanging out with Ashton's bandmate, Calum Hood, and some of their team. They had some drinks and decided to continue the party later on," the source added. "There was definitely chemistry between Kendall and Ashton. They certainly make an attractive couple - despite the complicated back story."

The pair already had a connection at this year's Billboard Music Awards. Kendall Jenner was chosen to introduce 5 Seconds of Summer's performance of "She Looks So Perfect," however she almost said One Direction's name instead.
