Ben Fogle was the proud owner of the Sport Relief Light Entertainment Boxing Belt after beating Sid Owen in the charity's Celebrity Boxing match.
The former Castaway heartthrob could also boast to being the undisputed people's champion after winning 68% of the public vote.
More than 130,000 votes were made within 15 minutes of the fight ending.
Owen shaded round one after an energetic start, but Fogle's stamina was the key as he finished on top.
TV presenter Fogle, 31, and former EastEnders star Owen, 32, have faced six gruelling weeks of training in preparation for the celebrity fight.
In the red corner, former Castaway heart-throb Fogle weighed in at a trim 12st 11lb, while his stockier rival revealed a fighting weight of 12-13.5.
But fitness proved crucial as Owen looked a spent force by the last of the three one-and-a-half minute rounds.
"I have only been training for a couple of weeks, but that is on the back of running the Sands Marathon, which is 150 miles across the Sahara Desert in six days, so I felt fit enough," said Fogle who, at six feet exactly, towered above his rival.
Owen had promised to "give it 200%" and was good to his word in a powerful start.
But his trainer Frank Maloney, who coached Ricky Gervais last year, was forced to accept a first-ever Celebrity Fight defeat.
Fogle was clearly delighted at surprising those who had believed he was "too posh to punch".
Following his patient performance he paid tribute to his trainer Jim McDonnell, who currently looks after British and Commonwealth heavyweight champion Danny Williams, and mentor Frank Bruno.
"I used to dread training with Jim but I owe so much to them," Fogle said.
In the true tradition of boxing, both fighters adopted menacing nicknames.
Animal Park presenter Fogle opted for "The Bear" because of his wildlife background and in honour of his Canadian father.
Hissing Sid Owen, whose mentor was former world featherweight champion Barry McGuigan, was known as The Snake.
