One of Rory McIlroy's best pals has split from his model fiancée Katie Larmour, the Diary can reveal.
The former beauty queen (29), who was once linked with Jonathan Rhys Meyers, has called off her engagement to amateur golfer Harry Diamond.
The couple had been due to wed in Italy next summer after the footballer went down on bended knee and proposed to Katie during a trip to Paris in October 2013.
Just two months later, his good pal Rory followed suit by popping the question to tennis pro Caroline Wozniacki, before calling it off a mere five months later.
But now both lads are firmly single, with Harry a constant companion to Rory on his many nights out as he celebrates his amazing string of Major wins.
Diamond has been photographed on numerous occasions with the Down native as they hit the tiles over the past few months, usually accompanied by a bevy of glamorous ladies.
He and Katie, who were one of Belfast's best-known celebrity couples, had been together for five years together and used to share a house in Holywood, Co Down.
She has told pals that she's intent on concentrating on her interior design business over the coming months as she takes her mind off the split.
Katie has no shortage of suitors, and has previously dated a Saudi Prince.
Ironically, she was recently named as the face of the Marine Court hotel's nuptial packages, which saw her looking suitably bridal in a series of gorgeous pictures.
She also has Belfast Fashion Week to look forward to, given that it starts today and runs until October 19.
