Even grandma tagged along for the fun!

Jennifer Garner and son Samuel showed their support for Red Nose Day in Brentwood this afternoon, and the actress' mom Patricia even donned the goofy accessory to raise awareness for the good cause. So what's Red Nose Day, you ask?

"Red Nose Day brings people together to have fun, raise money and change the lives of kids who need our help the most. Red Nose Day launched in the US in 2015, dedicated to ending child poverty, both in the US and in some of the poorest communities in the world. The money raised by Red Nose Day in the US has benefited programs for children and young people in all 50 states and in 25 countries internationally," their website reads.

Another person involved in Red Nose Day? Jen's ex Ben Affleck! While chatting about the charity, the Oscar winner revealed he'd love to direct a female-led film, specifically one starring his former wife.

"I would love to, are you kidding me? I think that would be great. I’ve often said that I want to direct a movie that Jennifer was in because I think she’s so great and she could do something really cool. The problem that gets in the way is that one of us has to be looking after the kids at home," he told People.

Jen G's passion has always been children, and it's nice to see that feeling isn't limited to just her own kids!
