Jennifer Garner looks beautiful as she goes make-up free while carrying son Samuel, 4, in her arms for departure from London

Jennifer Garner departed London on Thursday, carrying her adorable son Samuel in her arms.

The 44-year-old actress - who has been spending time in the UK with her estranged husband Ben Affleck and their three children - looked in a great mood as she walked through Heathrow Airport with her youngest's arms wrapped around her neck.

Going make-up free, the gorgeous Hollywood star cut a glowing figure, her defined features and flawless complexion no doubt catching the eye of onlookers as she made her low-key journey towards her flight.

She had dressed comfortably for her flight, teaming a pair of cosy slightly fitted white jogging bottoms with a monochrome top.

Adding some warmth to her ensemble to battle against the unusually chilly British June weather, the 13 Going On 30 star also sported a chunky quilted blue jacket.

Her brunette mane was slicked back away from her beautiful face, which was often seen smiling as she chatted to her four-year-old son.

The little boy - the younger brother to Jennifer and Ben's two daughters, Violet, 11 and Seraphina, seven - flashed a small grin as he chatted to his mum, before the pair headed off on their journey, perhaps back home to Los Angeles.

Almost a year after splitting from Ben, 43, there are now reports that the couple could be set to reconcile, despite claims that he had cheated on Jen with the family nanny.

Friends of the former couple, who have spent much of their time together in recent months, have told Us Weekly that they are heading towards a full reunion.

Put your best foot forward in Brunello Cucinelli trainers

As Jennifer Garner departed London, she donned very casual attire.

The actress was dressed in a comfortable jeans, shirt and trainer combination that was no doubt perfect for travelling internationally.

Despite the off-duty approach to her look, it certainly didn't come cheap. The footwear for starters was over $1400

Jennifer's trainers are by Brunello Cucinelli and the beige pair feature a beaded stripe to each side, providing a bit of much needed sparkle.

A number of sources spoke to the magazine about the changing nature of the former couple's relationship, as they are spending the summer in Europe.

With Ben based in London while he films The Justice League: Part One and his estranged wife joining him with their children, the pair have been spending a lot of time together away from the stresses of Hollywood.

And, according to Us Weekly it's working, especially after yet another quick getaway.

Last month they headed to Paris for a mini vacation and, more recently, went to Italy and stayed as a family, at Venice's Gritti Palace hotel.

A friend of the couple told the magazine that the mini getaways had helped rekindle the flame between the pair and while they are not back together, Jen is changing her tune and open to it.

The friend told Us Weekly: 'Jen would definitely get back together with him.'

Another insider elaborated saying the trip had helped mend the wounds of their hearts. 

The source said: 'A lot of damage has been mended. They are really in a good place.'

However, Ben's camp do not seem to be so helpful, with insider telling the magazine it was strictly about the children.

The Ben source said: 'They're co-parenting while he's filming. That's all it is.' 

Reunion on the cards? Almost a year after splitting from Ben, 43, there are now reports that the couple could be set to reconcile, despite claims that he had cheated on Jen with the family nanny
