'I'm not entirely sure my old access pass works...' Dr Chris Brown is leaving Channel Ten.

Everyone's favourite TV vet, Dr Chris Brown, is officially leaving Channel Ten.

The 44-year-old will leave the network in July, after being poached by Channel Seven, according to The Daily Telegraph.

But before he makes the move back to his old network, Brown will co-host his final season of I'm A Celebrity… Get Me Out Of Here!, which will air in April.

"I'm not entirely sure my old access pass works but once we get over that hurdle and I’m back from the jungle, I can’t wait to sink my teeth into some exciting new projects in the second half of the year and beyond with Seven," Brown said in a statement released by Seven today.

According to news.com.au, it's believed Brown will be on a two-year contract with Channel Seven, worth over $1 million a year.

Brown originally got his start in TV at Seven back in 2003, when he appeared as a vet on Harry’s Practice.

He later jumped ship to Channel Nine as a presenter on Burke’s Backyard before he moved over to Channel Ten for Bondi Vet in 2008. 

Most recently, Brown co-hosted Channel Ten's The Living Room, before it went on a 'hiatus' last year.

Speaking to The Daily Telegraph in December, Brown said he wasn't sure if the show would return to our screens this year. 

"I think you’d have to check the TV dictionary," he told the publication. 

"The Oxford TV dictionary defines hiatus as cloudy with a chance of coming back but it is very unclear. Who knows what is happening."

While it hasn't been confirmed what Brown will be involved in on Channel Seven, Seven West Media boss, James Warburton, said in a statement that the network "can’t wait to have [Brown] on board and to announce the great new content he will star in."
