The reports come amid claims he's set to follow in the footsteps of Sylvester Stallone by fronting a Warbuton's commercial.

A source told The Sun: 'Warburtons absolutely love getting big names to front their adverts and they don't come much bigger than De Niro. They've set the bar higher than ever.'

It's reported that the actor has travelled to the UK to film the commercial at a secret location.

Warburtons is a family-owned British company founded by Thomas Warburton in 1876.

The brand, that's based in Bolton in the north of England, is the largest bakery brand in the UK.

It comes on the heels of news that De Niro and his wife of 21 years Grace Hightower, 63, have separated.

PageSix.com claimed on Tuesday that the Goodfellas and Raging Bull star and Hightower 'are no longer living together.'

The couple have two children together - son Elliot, 20, and daughter Helen, six.

It is not the first split for the pair, who were wed in 1997.

Two years after their marriage, De Niro filed for divorce two years but it was never finalized.

They later reconciled and went on to renew their vows in 2004.
