Ten months after announcing their separation, Jennifer Garner and Ben Affleck spent some quality family time with their three children Violet, Seraphina and Samuel. The estranged couple were spotted arriving at the St. Pancras International train station on Sunday after spending the Mother's Day weekend in Paris.

"They were pretty relaxed and just walked through the main concourse of the station with their bags. They didn't really say anything but seemed in good spirits and were smiling a lot. It was all very chilled out," a source told People.

Following the Paris escapade, they spotted spending some "happy family time" without their bodyguards, confirming the duo's claim that the happiness of their children is their first priority.

"They were in a really good mood. They were laughing and joking with each other. It was really nice that they had no bodyguards with them. They were like a regular family coming back from a holiday," the same source added.

According to the news outlet, the famous Hollywood family reached Paris last Thursday (5 May) and reportedly shared a family apartment together at Le Pavillon de la Reine. A source also claims that both Affleck and Garner appeared happy and "affectionate" in each other's company during the holiday.

"At first, they were alone and appeared to be affectionate, then were joined by the kids," an onlooker told the website. The Hollywood couple had garnered a lot of attention during their separation but made it clear that their children will be their first priority.

Affleck is currently filming The Justice League Part One movie in London. Previously, there were rumours that the 44-year-old American actress was pregnant with her fourth child with her estranged husband. However, none of the star's spokesperson confirmed it.
