Jennifer Garner just had her best viral meme.

On Sunday, the "Peppermint" actress graced the Oscars red carpet in a royal blue Atelier Versace gown. But what made that night more memorable for Garner's fans was when she was caught on camera with a sudden deeply grave expression as if she remembered something so important.

Some were wondering why Ben Affleck's ex had a sudden change of expression. "What realization did Jennifer Garner just come to?" Bobby Finger asked.

Garner's fans immediately shared their funny thoughts on Twitter. A number of them believe that the "Love, Simon" star forgot something at home.

"Jennifer Garner just realized she forgot to take the chicken out the freezer," Jasmine wrote.

Another one captioned the same clip with yet another funny message. "Did I turn my straightener off," TheresaRockFace posted.

"Left oven on at home. stars: they're just like us," Bubbie's T'Challa Recipe wrote in response to Finger's question.

A number agreed that if Garner forgot something at home, it could be leaving her oven on. The "13 Going 30" is popular with her pretend cooking show where she shows off her baking skills and shares her recipe. However, not all of her pretend cooking shows were successful.

In February, the "Miracles from Heaven" actress shared a clip of herself attempting and failing to make bagels. According to her, she was very proud of her homemade bagels on Christmas, so she tried to make it again.

The short clip featured Garner preparing and mixing the ingredients. Unfortunately, things did not turn out well. The bagels were deformed and it ended up in the trash bin.

Although Garner's bagels were not successful, the actress is skilled in the kitchen. In fact, last Thanksgiving, she wished that Affleck and his mom, Christine Boldt, would take out their three children Violet, 12, Seraphina, 9, and Samuel, 6, outdoors and leave her in the kitchen to cook for them.

"If they will play with the kids and just let me cook, it is heaven for me," Garner said. "I will make homemade bread, I'll make stuffing, I'll make a turkey, I'll make gravy, I'll make sweet potato pudding, I'll make pies. Just let me have that day in the kitchen."
