Is Kendall Jenner dating Harry Styles?

Although the couple began the year together by vacationing on a yacht, their relationship has been up and down ever since. That said, during Jenner's 21st birthday, Styles was one of the many famous faces who showed up and showed his support for the reality star and model.

“Kendall Jenner was overwhelmed when she received a surprise special visitor first thing in the morning on her birthday,” a source told Hollywood Life on Thursday. “Harry Styles wanted to be one of the first people Kendall saw on her actual birthday and so he came by to personally deliver his birthday gift to the supermodel.”

Jenner and Styles spent time together earlier this year in Los Angeles, but by March, rumors began swirling in regard to her possible romance with Los Angeles Lakers player Jordan Clarkson and the two were spotted often in L.A.

While Jenner and Clarkson have continued to be spotted together since March, the latest reports have hinted that Jenner may be headed for a reunion with Styles.

“Harry drove over to her Los Angeles home around 10:30 am on Nov. 3, and stayed for only an hour,” continued the insider. “Which was plenty of time to show Kendall how important she is to him.”
