Kendall Jenner is reportedly trying to rekindle the romance with her former flame, One Direction's Harry Styles.

According to Daily Star, the 18-year-old reality star is sure that she and the 20-year-old singer are soul mates and regretting the couple's split. "The few times Kendall's seen Hazza since their split have made her all the more desperate to get her claws into him again," a source close to Jenner revealed. "She believes he's 'The One' and has been telling all her friends they are meant to be together."

"They only broke up because they realized a long-term relationship wouldn't be realistic with their heavy work commitments," the source continued. "But now she bitterly regrets agreeing to call it quits and is certain she can rekindle the fire between them."

Jenner is apparently very desperate to get Styles back, to the point that she has already purchased the VIP backstage passes for several shows from 1D's ongoing "Where We Are" world tour -- including both nights at the MetLife Stadium in East Rutherford, New Jersey on Aug. 4 and 5.

However, friends close to the "Keeping Up with the Kardashian" star are worried that her determined plan may backfire on her. "If she isn't careful, her neediness might drive Harry further away, rather than bringing them back together."

Meanwhile, the "Midnight Memories" hitmaker and New York-based model Paige Reifler, who were first romantically linked last year, were seen flirting with each other at the Warner Music & GQ Summer Party in London on July 17.

"Harry turned up specifically to meet up with Paige but they were as discreet as possible at the event," a source revealed to The Sun. "They then both left the main party, which was on the rooftop next to the pool, and went downstairs to the more private restaurant. They were having drinks with her agents."

"But Harry ended up putting his arm around Paige and they were flirty together. They ended up leaving on their own because there were lots of photographers outside," the source added.

Reifler also addressed the dating rumors with Styles recently. "I went to the Warner party at Shoreditch House with a friend and saw him there," she told The Mirror. "The next morning I woke up and I was in all of the newspapers and magazines. I wasn't expecting that, it's not like that in New York."

When asked if she is dating the British singer, the blonde beauty said: "Yes, I am seeing him."
