Jennifer Garner shared a new revelation about one of her kids.

The "Tribes of Palos Verdes" actress shared on her Instagram Stories a photo of the treats that her kids prepared and left for Santa and her reindeer. The snap featured cookies, milk and apple on the table. It also included a note that read: "I love you Santa."

However, not all of her three children are huge fan of Santa. In fact, one of them does not believe with Father Christmas anymore, Just Jared reported.

"I still have two believers," Garner captioned the photo.

Garner did not drop a name, but the publication guessed that Garner's eldest daughter with ex Ben Affleck, Violet, is the one who doesn't believe in Santa anymore. The 12-year-old is more grown-up compared to her siblings Seraphina, 8, and Samuel, 5.

In fact, Violet celebrated her 12th birthday earlier this month without her parents. Garner and Affleck's eldest was spotted at Barton G. restaurant in Los Angeles dining out with a group of friends. She was accompanied by a nanny.

Violet and her friends shared lobster pop tarts for their meal. They also enjoyed cotton-candy for dessert that was delivered in a fluffy pink confection atop Marie Antoinette's head.

Although Affleck and Garner were missing on her birthday celebration, the ex-couple were spotted together earlier that day. They were seen strolling in the L.A. neighborhood.

Affleck and Garner remained amicable after their split. The "Daredevil" stars have agreed to co-parent their children and they are working together for the best of their kids. In fact, Affleck has continued his alcohol rehabilitation.

A few weeks ago, the "Justice League" star was spotted leaving a residential facility. On the said sighting, Affleck looked unstable. He was accompanied by two women, who were believed to be his coaches.

Earlier this year, Affleck announced that he just completed an alcohol addiction treatment. He even thanked Garner for looking after their kids while he was away for rehabilitation. The "Batman" star confessed that he did it to be the best dad for his three children.

"I have completed treatment for alcohol addiction; something I've dealt with in the past and will continue to confront. I want to live life to the fullest and be the best father I can be," Affleck wrote on Facebook. "I'm lucky to have the love of my family and friends, including my co-parent, Jen, who has supported me and cared for our kids as I've done the work I set out to do."
