The two met while filming the upcoming film Deep Water and they formed a connection. In March 2020, they sparked dating rumors after they were spotted visiting Cuba and then Costa Rica. One person named Luz told E! News at the time she even met Ben and Ana in the VIP area of the Cuban Art Factory.
After they returned to California later that month, they quarantined together. But photographers spotted the pair kissing while out on a walk. At the time, a source said they looked like "total lovebirds."
"They can't get enough of each other," an insider said. "After days of being quarantined and never leaving each other's' sides, they are still laughing, smiling, kissing and hugging."
On April 30, 2020, Ana's birthday, the stars became Instagram official. "Thank you all so much for the birthday wishes and love!" the Knives Out alum wrote on Instagram alongside a few photos with Ben. "Cheers to another great year."
The following month, Ben and Ana continued to pack on the PDA by appearing in Residente's star-studded music video, where they shared some sweet kisses.
That same month, Ana also met Ben's kids, who he shares with his ex-wife actress Jennifer Garner. "Ana loves kids and couldn't wait to meet them and spend time with them," a source told E! News at the time. "She knows how much they mean to Ben and so she was anxious to be a part of that. She is very sweet and kind to the kids. They immediately warmed up to her and like her a lot. They are all comfortable together and she's very nurturing. Everything has worked out very well."
In May, the two appeared to still be going strong. "She supports his sobriety and has really helped him stay on track," an insider also told E! News at the time. "She is loving, caring and fun. They are always laughing and making each other smile. Ben is extremely happy with her...Everything seems to work between them, and it's been a long time since he has fallen hard like this."
In August 2020, it was Ana's turn to celebrate Ben's big day. The two marked the major occasion with a sweet selfie.
In November, the two traveled to New Orleans, where a source said they were "hard at work on reshoots for Deep Water." Still, they managed to enjoy some one-on-one time together, too.
"Ben seemed ecstatic to see Ana again after he hadn't been with her for a few weeks," the insider said. "They were so happy to be around each other and couldn't keep their hands off one another."
At the end of the month, Ben and Affleck celebrated their first Thanksgiving together. A source told E! News Ben's kids came over to his house, where they spent Thanksgiving weekend with him and Ana.
