Kendall Jenner might want to consider beefing up her security, if she hasn't already, as her rumored romance with One Direction star Harry Styles reportedly heats up.
The 18-year-old model apparently began dating the 19-year-old British boy band member late last month. On Sunday (Dec. 15), Styles was spotted arriving at Jenner's hotel at 2:20 a.m. -- adding fuel to the rumor fire.
The Daily Mail reports that Styles ditched his bandmates and flew over to London to meet up with Jenner, after they picked up the awards for Video of The Year and International Duo/Group of The Year at the prestigious annual NRJ Music Awards at the Cannes Festival Palace in France.
Jenner has chosen to remain tight-lipped on the subject of their relationship. When asked about her alleged romance with Styles, she told E! News she had "nothing to say. No deets." The One Direction singer played it just as coy when he sat down with CNN’s Piers Morgan.
Rumors that the two were dating began in late November after they were spotted enjoying a dinner date at Craig's in West Hollywood. The pair made headlines again after it was reported that Jenner was waiting backstage for Styles while he performed on "Saturday Night Live," and the two unexpectedly hit up Therapy, a popular gay club in Manhattan's Hell's Kitchen after the show.
Though Jenner and Styles don't seem ready to take their relationship status public yet, a source told the Daily Mirror that the pair has been texting "constantly," and are "both excited about the relationship."
