Harry Styles Cheating On Kendall Jenner? Meet Haley Giraldo, The One Direction Singer's Rumored New Girl [PHOTO]

Trouble in paradise? Less than 24 hours after rumors starting circulating that singer Harry Styles and his girlfriend, reality TV star Kendall Jenner, were engaged, there is already buzz that the One Direction member may have eyes for another woman.

According to a report from Star magazine via ShowbizSpy.com, the 20-year-old "What Makes You Beautiful" performer was spotted leaving Swingers restaurant in Los Angeles on Jan. 26 with a woman, reportedly not Jenner, waiting in his SUV. After following Styles' alleged date, the magazine is now reporting that the mystery lady in the singer's life is named Haley Giraldo.

"They talk almost every day when he's home in London," a source told the magazine, adding that the British singer has been known to frequently send Giraldo "romantic gifts" after meeting her last year at a concert.

According to the insider, the duo's romance has only recently been discovered by Styles' girlfriend of three months, "Keeping Up With the Kardashians" star and print model Kendall Jenner. "They've been trying to keep it on the down-low," said the source, adding that the 18-year-old TV star was devastated to hear of the betrayal. "It hurts to find out they weren't exclusive like she thought," said the source.

So just who is Styles' alleged new leading lady? While Giraldo may not be as big as a name, she does have ties to Hollywood. Giraldo, who has made a name for herself on sites such as The Dirty, is reportedly the 29-year-old daughter of Pat Benatar of "Hit Me With Your Best Shot" fame.

While there is no comfirmation that the duo are an item, Giraldo hasn't been shy about making her relationship, whether romantic or platonic, with Styles public. The blonde beauty has not only recently tweeted her best wishes to the singer on his 20th birthday on Saturday, she also recently admitted to having an in-depth discussion about his band with a friend on Twitter.

On Tuesday, Styles and Jenner were rumored to be engaged after Directioner fans circulated what is believed to be a photoshopped picture of the young couple's engagement announcement on social media. The image of the pair, which was joined by the hashtag #CongratsHendall, claimed: "Today at 6:00 PM, Harry proposed to Kendall Jenner and she said yes. If you support them and will still be a directioner, repost this and tag this to: #CONGRATSHENDALL.”
