Ben Affleck and Jennifer Garner presented a united front on Sunday while they spent time with their children at the Pacific Palisades Farmers' Market in California, shopping for toys and later hosting a quiet, end-of-the-school-year gathering for daughter Violet, 9, and some of her friends. Children Seraphina, 6, and Samuel, 3, were also in tow.

“Jen decorated with balloons and set up a party in the backyard,” a source told People on Thursday. “Violet’s friends’ moms were invited, too.”

Affleck and Garner also were seen the next day at Violet’s school and then at the Brentwood Country Mart to pick up some toys. A source also told People that the couple purchased art supplies, a game and a sticker book that Seraphina chose for Violet.

"Jen and Ben were really focused on Seraphina," the source added. “And she was loud and happy."

Rumors that the married couple are going through a rocky period surfaced in late May, when unconfirmed reports claimed the two were leading separate lives. Rumors claimed that the “Batman v. Superman” actor's love for blackjack could be causing tension between the couple, and Affleck confirmed that he was banned from the blackjack table at the Hard Rock Hotel & Casino in Las Vegas last September.

"That is a true story. I mean, that took place," he told Details magazine. “I took some time to learn the game and became a decent blackjack player. And once I became decent, the casinos asked me not to play blackjack. I mean, the fact that being good at the game is against the rules at the casinos should tell you something about casinos." He denied he had a gambling problem.

It didn’t help that the filmmaker called his marriage to Garner “work” while accepting his Oscar for “Argo” in 2013. “I want to thank you for working on marriage for 10 Christmases. It’s good, it is work, but it’s the best kind of work, and there’s no one I’d rather work with,” he said.
