They cooled off after getting hot and heavy while on vacation together over the holidays earlier this year, but now a source tells PEOPLE exclusively that Kendall Jenner and Harry Styles are back on.
The duo were spotted on a dinner date at L.A. hot spot Ysabel on Thursday night, and the model "was beaming" all night, says an onlooker.
According to a source close to Styles, 22, and Jenner, 20, the duo "are trying to spend time together again" after cutting off their relationship for a bit.
"They're rekindling their old romance and Kendall's so excited and happy about it," says the source. "She's always cared about Harry."
The stars first met a few years ago, but "things never got serious," a source told PEOPLE earlier this year about their New Year's vacation. "He has thought all along that Kendall is hot and was sort of just waiting for a chance to spend more time with her again."
The Keeping Up with the Kardashians star and the singer were first linked in January 2014 when they were seen going out to dinner and hitting the slopes at Mammoth Mountain in California.
