Putting break-up rumours to rest, Brad Pitt and Angelina Jolie put on a public display of affection at the Super Bowl American football final and have also issued a legal statement insisting they have no intention of ending their relationship.

Lawyers for the couple today said they are not about to split and would consider suing any media outlets that continue publishing the 'false allegations'.

Dailymail.co.uk reports that the legal move follows weeks of speculation about their five-year relationship, with reports suggesting they have signed legal papers over their about $320 million fortune and custody of their six children.

Jolie, 34, and Pitt, 46, have previously ignored growing rumours that all is not well in their relationship.

Their public denial comes just hours after the Hollywood couple brought their eldest son Maddox, 8, to watch the New Orleans Saints beat the Indianapolis Colts at the Sun Life Stadium in Miami Sunday.

During the game, the couple were seen kissing, hugging and laughing together as they cheered on the Saints' dramatic victory which provided such an emotional moment for the city of New Orleans, devastated by Hurricane Katrina in 2005.

As they watched the game, the two gave photographers plenty to watch as they cuddled up for the cameras.

With Jolie dressed down in her signature black, the couple hoped to make a low-key entrance as they dashed through the stadium to take their seats for the big game.

It was the first time they'd been pictured together in over a month - after last being photographed out dining in New York on Jan 6.

Pitt and Jolie both attended the Directors Guild of America Awards over a week ago, but arrived separately and declined to be photographed together.

While not known for their huge interest in American football, Pitt and Jolie are big supporters of New Orleans and own a $3.5 million 1830s house in the historic Louisiana city.
