Casey Affleck, 46, has gone public with his romance with actress Caylee Cowan, 23, only days after the first photographs of them making out was published.

The Manchester By the Sea actor, who is known for keeping details of his personal life discreet, revealed that he is dating actress Caylee Cowan on Instagram.

On November 25, he acknowledged his relationship with Cowan by uploading a photo of the two together and called her ‘My love.’ This came as the duo donated blood to the Red Cross.

“@cayleecowan showed up,” he said alongside photos from the Thanksgiving event, including a snapshot of Cowan reclining on a bed while donating blood. “She is not on the Love’s active roster, but she is MY Love, and she ALWAYS shows up when it counts.”

“However Caylee is usually unenthused about needles, blood, etc, and though she believably feigned nonchalance all the way to the donation location, once on the table with her sleeve rolled up, she was overheard quietly asking a staff member, ‘Is there a chance I might die?'” Affleck shared.

“The answer was no, of course. Donating is not only SAFE but PAINLESS and QUICK,” the Oscar winner added.

Cowan, 23, was hesitant to donate, according to Affleck, 46.

Other Love teammates who gave blood to the charitable organization, including Mets pitcher Brian Nichol, designer Kody McCarty, and Jon Hamm, were recognized in Casey’s message.

“First baseman, and all around real life superman, @jonhamm_officially was in the house to give his incredible DNA to someone who might need it,” he shared, before quipping, “[I asked if I could have some of Jon’s blood, and if it would make me better looking, but I was told ‘No, and probably not.’]”

Cowan said on her beau’s Instagram photo, “I love you so much.”

The pair then went on to encourage their fans to give blood.

“The Red Cross needs your help this Thanksgiving. Blood or platelet donation is needed now to prevent delays in patient care. Hospital demand continues to outpace donations, and your help is vital. This is serious! Emergency shortage of lifesaving blood, especially type O, and platelets. The blood supply is at the lowest level the Red Cross has seen at this time of year in 10+ years,” she penned.

The couple’s relationship declaration comes just days after they were photographed getting cuddly during an excursion in Los Angeles on Tuesday, November 23, as per images acquired by Page Six. The two weren’t hesitant about showing off their PDA in the photos, as they were seen holding one other tight and enjoying a passionate kiss.
