Jennifer Garner out with her three costumed Halloweenies

She’s truly a mom for all seasons.

Jennifer Garner on Tuesday was snapped in Los Angeles walking with her three children, who were clad in their Halloween costumes.

The 45-year-old Alias actress wore an off-white sweater and blue jeans with brown shoes and a tan purse as she led the way for her children with ex Ben Affleck, Violet, 11, Seraphina, eight, and Sam, five.

Happy day: Jennifer Garner, 45, was snapped in Los Angeles Tuesday with her three children (L-R) Sam, five, Seraphina, eight, and Violet, 11, all of whom sported different Halloween costumes

The Golden Globe-winning star had her brown locks pulled back and wore black sunglasses while also toting some bags for her kids on the special day.

The kids went with different looks, with Violet wearing a Pirate’s hat and top with black pants and boots, while Seprahina went in a medieval green Robin Hood outfit. Sam, wearing a red bandanna cap with white sideburns, carried a toy sword and wore a blue shirt with horizontal stripes and blue shorts, looking very much in the spirit of the day.

The Dallas Buyers Club actress has made clear she’s a huge fan of the fall season in recent posts on her Instagram account, as earlier this week, she documented a trip to the pumpkin patch.

‘Some see jack-o-lanterns, I see muffins. These very exact specific muffins,’ she wrote, accompanying a pair of photos in which she relaxed along the side of an enormous squash, and pushed a wheelbarrow loaded with them.

The mother-of-three on Monday shared another shot in which she stood alongside three scarecrows modeled after her three kids, and even wearing their clothes. She wrote, ‘TO THE CROWS: BOO!’ adding the hashtags, ‘#quieterthanthehumanversions,’ ‘#familytradition,’ and ‘#ohpleaseyesihadhelp.’

When she’s not with her kids, or coming up with creative complements to the fall foliage, Jen’s in the business of doing good deeds, as she opened up to People earlier Tuesday about her efforts last month assisting with aiding her birthplace of Houston following August’s devastating Hurricane Harvey.

Garner, who works with the nonprofit Save the Children, shared a heartwarming story with the magazine about one of the children she encountered in Texas.

‘One boy told me how his mom had put the kids in a kiddie pool in chest-high waters, and she had gone under because she couldn’t swim,’ she told the publication. ‘He’d said, “Throw Mama a rope!” and saved her. Instead of saying, “We lost our house, all my toys are gone,” he wanted me to know that his mom was okay. That spirit makes you really appreciate the good in the world.’

The Tribes of Palos Verdes actress encouraged her fans to pay it forward as she has, through either Save The Children or other philanthropic efforts.

‘Sponsor a child through Save, do a book drive, donate diapers … just help in some way,’ she said. ‘Be your own kind of first responder. It will restore you and your faith in humanity.’
