Kendall Jenner Dating Secret Boyfriend? Instagram & Twitter Rumors Surround KUWTK Star

Keeping Up With The Kardashians (KUWTK) star Kendall Jenner is rumored to secretly be dating 5 Seconds of Summer singer Ashton Irwin.

"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," a source told The Mirror.

Last week she posted a photo on Instagram and Twitter of herself in a Bruce Weber photo, where she is spotted half naked under another under-dressed male model.

Could the KUWTK star be dating a new boyfriend?

She is rumored to have upset her sister Kylie following rumors she was dating Justin Bieber.

"Kendall knows full well that her sister loves Justin. Kylie's been desperate to date him for a long time, so for Kendall to hook up with him is pretty poor form," a source told J14.

"LA is nine hours behind Spain, so it was the middle of the afternoon when Kylie saw Kendall's steamy Instagram pictures with Justin. She tried to pretend that she didn't care, but she was close to tears. It's caused a major split in the family, with everyone taking sides."

Rumors of her dating boyfriend Justin Bieber following her break up with Harry Styles grew following pictures of them getting cozy in an Ibiza nightclub some time ago.

However, Kendall Jenner may to want to end her break up with Harry Styles and continue dating her ex-boyfriend.

"The few times Kendall's seen Hazza since their split have made her all the more desperate," a source told the Daily Star.

"She believes he's 'The One' and has been telling all her friends they are meant to be together."
