Mike Tindall's son Lucas showed he was eager to join in at a charity football match today where his father was playing alongside football royalty in Gloucestershire.

The young football fan, who will celebrate his third birthday on March 21, was also seen cheekily sticking out his tongue as he was picked up by his father at the game. 

His enthusiasm was clear as he clambered over the fence to join the other players at the 'Battle of the Balls' match on Sunday as he was helped by mum Zara Tindall, the King's niece.

Lucas cheered on the players, who included Harry Redknapp and Nick Knowles, from the sidelines as Zara handed her youngest child a fruit drink.

Hollyoaks actor Owen Warner - who was Tindall's I'm a Celebrity... campmate - also joined the match at the Tigers Turf Stadium, the home of Gloucester City Football Club.

The charity event pitched a World of Football team against a World of Rugby squad, captained by Tindall and managed by Harry Redknapp.

Their rivals were led by former Brighton and Hove footballer Ken Blackburn. 

Tindall clearly gave the match his all, photographed in pursuit of the ball in his red-and-blue World of Rugby strip. He later posed for pictures with other celebrities in attendance.

Explaining the aim of the charity, Battle of the Balls said: 'Professional sports can take a heavy toll on the body after a number of years playing at the highest levels, but retirement doesn't mean the players have any less heart when it comes to wanting to win.

'Sportsmen, during their downtime, enjoy playing a number of alternative sports to their chosen profession including golf, football, tennis, cricket, basketball, and snooker to mention just a few. 

'An idea was formed which was to become the Battle of the Balls: the idea to pit the Rugby for Heroes team against other teams made of similar ex-professional players but the twist is they play on their home turf and at their own sport too.

'Months later we are at the start of our next journey with the squad as they take on this latest challenge.'

Earlier this month, much to the delight of fans, I'm A Celebrity... Get Me Out Of Here!'s Mike and Sue Cleaver reunited for a 'gorgeous sneaky lunch'.

Coronation Street star Sue, 59, who formed a close friendship with the former rugby ace when they were in the jungle together, took to Instagram to share a picture from their get-together.

The actress was all smiles as she posed for a selfie with the beaming ex England Rugby star outside a luxurious-looking restaurant.

Posting the snap online, she wrote: 'Gorgeous sneaky lunch with one of my husbands - sorry to my other ones, your time will come #junglehusband #junglehubby @mike_tindall12 #imaceleb.'

Wrapping up against the cold, Sue donned a padded navy jacket for the outing, while Mike, 44, opted for a fashionable brown cardigan.

Fans were quick to comment on the photo, with one person writing: 'Lovely that you've remained friends.'

Another said: 'Good to see you both staying in touch outside of the jungle. Everyone says they will but they probably don't. It's a great picture.'

Following their time together in the jungle, Mike's wife Zara Tindall, 41, playfully accused her husband of 'cheating' on her with his 'camp wife' Sue.

The royal touched on her former rugby pro husband's close friendship with the actress on The Coming Out Show in November. 

After meeting him on the jungle bridge, Zara and Mike travelled back to the hotel together and Mike says: 'I'm sorry I had a camp wife in there, but she was brilliant.' 

And Zara joked: 'Cheating on me!'

Before meeting Mike, Zara sweetly told cameras: 'It's been a long few weeks, the kids have missed him so it'll be nice to get him out.'
