The contract shows that Ross is still one of TV’s highest paid chat show hosts, despite leaving the BBC in shame last year.

His existing deal was due to expire at the start of next year, but The Jonathan Ross Show will now stay on screens until early 2013.

Ross, 51, will present three series of the chat show, with 10 episodes each plus Christmas specials.

The Jonathan Ross Show has so far hosted Jamie Oliver, Lewis Hamilton and Lady Gaga, pullin in an average of 4.1 million viewers.

This year’s Christmas special will feature guests including Tom Cruise.

Ross worked for the BBC until last year, where he was the corporation’s highest-paid presenter, reportedly earning around £5.7m a year for his TV and radio shows.

He was suspended for three months after he and his Radio 2 co-host Russell Brand left a series of smutty phone messages for 81-year-old actor Andrew Sachs about his granddaughter.

Ross then took a break from television and Graham Norton took over his radio show, before he began his show for ITV in September.

Ross said: “I am thrilled to be signing again for ITV. It’s like that stage in a relationship when you’ve been leaving a few clothes over every time you stay, and they finally give you a door key.”
