Tomic quits the jungle, vows to focus on tennis

Bernard Tomic has expressed a heartfelt desire to resurrect his tennis career after becoming the first person ever to quit 'I'm a Celebrity ... Get Me Out of Here'.

On Tuesday night's episode of the reality TV show, rumours that Tomic had quit were confirmed.

"I wasn't sure if I should come in the first place," Tomic told his fellow 'celebs'.

"I've wasted this whole last year not playing a lot of tennis and not being professional.

"I did start playing well a few months back so I need to be competing and playing and doing what I do best.

"That's why I've decided to leave."

He was also seen telling the show's producers "I need to get out of here."

Hawthorn premiership great Josh Gibson backed Tomic's decision, if it meant he was leaving to focus on tennis.

"Hopefully he delivers on that talent that we all know he's got," Gibson said.

Tomic's decision to leave the jungle comes on the same day Lleyton Hewitt admitted he is not sure whether the controversial star will even continue playing tennis.

Australian team captain Hewitt said he doubted whether Tomic would play Davis Cup again after causing a stir since joining the reality TV show.

Tomic told Network Ten that Australia could not win the Davis Cup title without him and that Hewitt knew it.

Tomic's comments didn't go down well with two-time major winner, who is preparing a Nick Kyrgios-led team for their Davis Cup first-round tie against Germany in Brisbane starting on Friday.

Asked if Tomic would play for Australia again, the former world No.1 said: "It's highly doubtful.

"He's made some mistakes. It will be a long way back.

"He's digging a big hole for himself that he may never get out of."

Kyrgios joined the squad on Tuesday but Hewitt said team members already in camp had laughed off Tomic's claim that they needed him to be successful.

"I don't watch a lot of those kind of shows but a couple of boys have kept a close eye on it (I'm a Celebrity) and it keeps them in good humour at night and gives them something to talk about," he said.

"The team camaraderie is as good as I have seen for a long time.

"We believe we can go a long way and I back these boys."

Asked if Australia could win without Tomic, Hewitt said: "Everyone knows he couldn't help us right now".

Baffled by Tomic's reality TV stint, Hewitt said the former Wimbledon quarter-finalist had to commit to the sport to ever be considered for Davis Cup again.

"It's strange. You either want to be a tennis player or you don't," he said of Tomic's TV reality show appearance.

"I don't know (if he will play again). He still wanted to play the Australian Open and tried to qualify and good on him for that.

"But it is pointless if he is playing in quallies and you are not committed to the sport.

"He's wasting not only his time but also everyone around him.

"He's got to commit to the sport if he has any chance of coming back."
