Ben Affleck could be seen enjoying a bonding moment with his son Samuel as they celebrated the little boy’s 12th birthday.

The 51-year-old movie star shares Samuel as well as his daughters Violet, 18, and Seraphina, 15, with his first wife Jennifer Garner.

Samuel was still in his basketball uniform on his birthday when he met up with his father, who sweetly carried his ball for him as they strolled down the sidewalk.

He had also come prepared with a wrapped gift for Samuel, which he balanced on one forearm while carrying a water bottle in that hand.

Warding off the February chill in a thick black coat, Ben modeled a sky blue t-shirt and hoisted on a pair of khaki trousers.

Ben and his ex-wife, who are famous for their warm co-parenting relationship, were also spotted reuniting and sharing a warm chat this week.

During a solo coffee run, Ben appeared in bright spirits, grinning as he crossed the street while bundled up in a hoodie.

On the romantic front, Jennifer is currently in a long-term on-off relationship with one John Miller, while Ben has married his early-aughts flame Jennifer Lopez.

Rounding off the blended family, J-Lo is bringing up a set of 16-year-old twins called Max and Emme, whom she shares with her third ex-husband Marc Anthony.

A source recently informed DailyMail.com that the J-Lo marriage has helped Ben and his ex-wife ‘get to a better place’ in their own equation.

‘Ben is healthy. The drama of the past and the emotions of divorce are long gone and they are all making it work,’ the insider explained.

Ben’s two wives are apparently ‘friendly’ with one another, and all of the children in the blended family are said to ‘love each other.’

The source shared: ‘It is really a very happy co-parenting situation. Everything is really good right now and should be the same in the near and distant future.’

A previous article on the UK website Closer Online claimed J-Lo was ‘blindsided’ and ‘furious’ at the sight of pictures of Ben and his ex-wife looking friendly.

Meanwhile Ben was claimed to be ‘saying Jennifer’s like his sister at this point and if J-Lo’s going to get jealous and throw tantrums over a harmless cuddle, then the problem’s on her. It’s a real war of attrition here that’s threatening to blow up.’

However, an insider assured DailyMail.com that Ben and J-Lo were ‘very much in love with each other’ and the rumors of tension in the marriage were false.

‘Their relationship is still on fire. They are really happy with each other, and there’s no drama in their relationship right now at all.’
