I'm A Celebrity is back with another star-studded celebrity lineup - and we're already obsessed!
Haskell is a former rugby player-turned-DJ and soon-to-be MMA fighter.
The 34-year-old has already insisted that he is like Marmite - in that the public will either "love him or hate him" - but has admitted it will be tough without his wife Chloe Madeley.
So who is James Haskell? Here's everything you need to know...
Which rugby teams has James Haskell played for?
With 77 England caps to his name, it's safe to say Haskell has had a pretty decent rugby career at the very highest level, also turning out for the British and Irish Lions twice.
Predominantly a flanker, he's also made a few appearances at number 8, playing club rugby across the world in England, France, Japan and New Zealand.
He started his career in 2002 at Wasps, before he moved to Stade Francais, the Ricoh Black Rams in Japan and the Highlanders in New Zealand - before then returning to Wasps in 2013.
In 2018, Haskell moved to the Northampton Saints before hanging up his boots in May 2019.
His honours include three Six Nations titles, including one Grand Slam in 2016, and an appearance in a World Cup quarter final in 2011.
He was also part of the side that whitewashed Australia during a summer tour in 2016 and also during Wasps' victory in the 2007 Heineken Cup. He also made the World Cup squad in 2015.
But he's not just a rugby player
Haskell's not exactly stood still since his retirement this year.
Alongside his impressive sports resume, Haskell is also a DJ, fitness fanatic and will turn out as an MMA fighter soon.
A relative newcomer to the world of DJing, Haskell spent the summer in Ibiza where he played to crowds of people.
Earlier this year, Haskell also announced he would be signing for MMA promotion Bellator, where he will fight as one of their heavyweights with his fight debut pencilled in for 2020.
But it's not just that - he's also built up a strong online following and has amassed around 238,000 Instagram followers for his health and fitness videos, often alongside his wife Chloe.
He also runs his James Haskell Health and Fitness business, and released a health cookbook recently.
His in-laws are pretty famous too
His wife of nearly a year is Chloe Madeley - the daughter of TV presenting couple Richard and Judy.
The couple started dating dating in 2014 and married at Christmas last year.
Chloe, 32, is also into fitness as well as working as a TV presenter and journalist.
He's not exactly compact
At six foot four inches and weighing an impressive 18 stone 8lbs, Haskell is somewhat of a man mountain.
But it's not all useless flab - his bodyfat often hovers around the 9-11% mark, and is used to eating six meals a day to maintain this.
So with the famously restrictive jungle diet of rice and beans, it'll be interesting to see how he gets on.
