Jennifer Lopez, Jennifer Garner and Ben Affleck weren't afraid to get loud over this special family milestone. 

The trio were all in attendance as Garner and Affleck's son Samuel,12, celebrated his graduation at the Good Will Hunting star's rental home in Brentwood, Calif., June 12. 

For the occasion, the Atlas actress was seen walking in through the front door donning a blue button-up shirt, white jeans and white Louboutin chunky heels, in photos obtained by Page Six. She topped off the look with silver hoops and a white Hermés Birkin bag.

The 13 Going on 30 star—who also shares kids Violet, 18, and Seraphina, 15, with Affleck—kept it casual in a light blue button-up shirt, green cropped coat, black slacks and black loafers. Meanwhile, the Justice League actor wore a classic blue suit and white button-up shirt for the party.

Samuel's graduation ceremony earlier in the day was also a family affair as Lopez's 16-year-old twins Max and Emme, whom she shares with ex-husband Marc Anthony, were on-hand.

But his celebration isn't the only milestone in the Affleck household. In fact, Violet graduated from high school in May and Garner—who split from the Oscar winner in 2015 after 10 years of marriage—couldn't help but shed some tears during the bittersweet moment.

"Tell me you have a graduate without telling me you have a graduate," she wrote on Instagram last month. "Bless our hearts." In the same post, she shared other photos of herself wiping away tears. "How are we going to make it?" she asked in one clip. "What are we going to do?"

And her fellow some celeb moms were quick to come to the rescue in the comments. "Oh honey ... I know," Reese Witherspoon wrote. "You have done a great job, mama! I will be here for support and lots of hugs."

Alias costar Gina Torres added, "Oh, sweet mama. You've kissed every boo boo and read every story and have made 5am breads and muffins. All while living your own big bad ass life. Ya done AMAZING!!!"
