The Saturday Night Takeaway star embraced the summer weather during the dog walk in a plain black T-shirt and navy shorts. 

Adding leather loafers and dark sunglasses, Ant cut a casually cool figure as he happily played with his Labrador Hurley in the sunshine.

Beaming from ear to ear, the star was seen lobbing a large stick across the grass, before excitedly egging his dog on to return it for another round.

Ant proved to be in good health as he soaked up the sunshine in the park, after battling through a number of rehab stints.

The presenter first sought treatment in June 2017, after becoming addicted to prescription drugs and alcohol following a botched knee surgery in 2015. 

While it was believed he had recovered, he entered rehab for a second time in March this year after he was involved in a three-car collision in Richmond - and was discovered to be over the limit behind the wheel.

He pleaded guilty to drink-driving in April, and received a record-breaking £86,000 fine, as well as a 20-month ban from driving.  

Aside from his health woes, Ant has also been battling through a bitter divorce with his ex-wife Lisa Armstrong since January.

While the Britain's Got Talent host is taking it easy in London, Lisa has escaped to Los Angeles for a holiday, and has been seen indulging in numerous shopping trips and beach days. 

The make-up artist was left devastated last month when Ant's new romance with his personal assistant and her former friend Anne-Marie Corbett emerged.

However, it has since been claimed that she and Anne-Marie never saw eye-to-eye, and that Lisa even booted her out of the home she used to share with the TV host last year, after a ferocious bust-up.

According to The Sun, the formerly 'firm friends' - with Lisa even attending Anne-Marie's daughter's baptism - have not spoken since she sacked her as her PA.

The publication went on to claim Lisa and Ant, who split after twelve years in January, are now only talking through lawyers, following a number of tense conversations over the phone.

Keen to smooth things over sooner rather than later, Ant has reportedly offered Lisa their multi-million pound home in Chiswick, in return for her signing the divorce paperwork.
