The 18-year-old model has secured backstage VIP passes for several One Direction shows and is determined to use the band's 'Where We Are' world tour to win back the hunky singer, 18.
A source told the Daily Star newspaper: ''The few times Kendall's seen Hazza since their split have made her all the more desperate to get her claws into him again.
''She believes he's 'The One' and has been telling all her friends they are meant to be together.''
However, friends close to the 'Keeping Up With the Kardashians' star are worried that Kendall's scheming plan may back fire on her.
The source explained: ''If she isn't careful her neediness might drive Harry further away, rather than bringing them back together.''
The pair - who were introduced to each other by their managers - began dating in November last year, but they called it quits just three months later after their conflicting schedules put a strain on their romance.
The source added: ''She bitterly regrets agreeing to call it quits and is certain she can rekindle the fire between them.''
Meanwhile, Harry is rumoured to be dating model Paige Reifler,18, again after they were spotted getting cosy over a few alcoholic beverages at an exclusive party at Shoreditch House in London earlier this month.
The actress thinks it would be tough to recast her character, Winifred Sanderson.
