Stewart was snapped holding hands with Cargile after the two had lunch at En Sushi in Los Feliz, California, on Sunday, both smiling as they strolled down the sidewalk hand in hand. Clad in a white T-shirt and baggy jean shorts, Stewart even matched with her rumored girlfriend, rocking black Vans socks while Cargile wore a pair of black Vans low-top sneakers.
"They were both in a good mood, smiling, and very animated towards each other," an eyewitness tells ET.
The two were also apparently not shy when it came to showing affection for one another.
"When standing outside their car, Alicia started hugging Kristen and kissing her on the neck," the eyewitness adds. "They were both aware that they were being shot, but were not shying away from the camera."
Monday marks the latest PDA sighting between the 26-year-old actress and her former personal assistant. Last Wednesday, the two kissed while out for coffee in Los Feliz.
Stewart and Cargile were actually snapped holding hands as far back as April 2015. But in March, the Cafe Society actress was spotted kissing French singer Stephanie Sokolinski in Paris, though according to multiple reports, the two split in May. Speculation that Stewart and Cargile rekindled their relationship started that same month, when the pair was spotted holding hands in Cannes, France, during the Cannes Film Festival.
"I've discovered a way to live my life and not feel like I'm hiding at all," she told The Los Angeles Times last week. "And I think that's pretty apparent for anyone who cares -- not that everyone does. But I think that if you had been tracking it in any way, it's more apparent that I'm more relaxed than I used to be."
