After performing with his bandmates in France, the 19-year-old jet to London for some fun. E! News confirms that the cutie, who was spotted wearing his signature skinny jeans and plaid flannel, made a stop at rumored flame Kendall Jenner's hotel late Saturday night.
The E! star was in London for a modeling photo shoot, and shared some pics from the trip on Instagram.
After having a rendezvous with Jenner, Styles spent his Sunday night partying at One Marylebone after One Direction's performance on The X Factor finale earlier that night.
The singer, who was hanging out with 1D film producer Ben Winston and wife, Meredith, seemed to be having a great time, because Harry wasn't seen leaving the wrap party until 3:30 a.m.
E! News also learns that Harry's ex-girlfriend Taylor Swift was hanging out in London last weekend as well. There's no word as to what the Red singer was up to, but we're sure there was some sort of celebration for completing her very successful world tour in Melbourne on Saturday.
Although Kendall continues to play coy on her relationship status with Styles, the pair have been spending a good amount of time together.
Prior to their London get together, E! News learned that the two dropped by Therapy, a popular gay bar in New York City, after the One Direction singer's Saturday Night Live gig. An eyewitness told E! News that the two "were having a great time" and "for sure looked like they were a couple. They had a blast."
