More than 250 friends and family - including some of football's biggest stars - have jetted to Argentina (right), 450 police officers are on duty and the bride's dress is said to have arrived from Spain on its own private jet accompanied by two bodyguards. But a source close to the Messi family told MailOnline that relations between his family and his fiancée Antonella Roccuzzo have been strained for nearly seven years. The Messi family dismissed reports of a feud between the families as 'nonsense'.

Messi and Antonella, who have two sons, have chosen to get married in their home town of Rosario, northern Argentina, where they grew up together.

The friend, who knew the Messi family before the footballer became famous and accompanied them on their first trips to Barcelona, said bad feeling first emerged in 2010, before the South Africa World Cup.

He said: 'An Argentinian interviewer was talking to Messi's mum about her and her husband going over to South Africa to see Messi play.

'He mentioned that Antonella was already there, and she declared: 'Antonella, Antonella, who's Antonella?

'It caused tension in the family, and Messi told his parents to stay in Argentina. The two families have struggled to be amicable since then.

The two families are staying apart at the same hotel during tonight's wedding celebrations, with the Messi family renting one floor and Antonella's family another, claimed respected news site ElIntransigente.com

Argentina's Noticias website also reports that the family fell out with the bride to be.

But the Messi family dismissed reports of a feud between the families as 'nonsense'.

A friend of the star added: 'The relationship between the families is really good, they get on really well and that's why they are getting married today.
