The 'jOBS' star uploads a personal photo of him kissing his girlfriend under a neon sign which reads 'SUN' on Twitter.

Ashton Kutcher, who has been keeping his relationship private with Mila Kunis, shared a PDA-filled photo on Twitter on Tuesday, December 10. The "Two and a Half Men" star uploaded a photo of him kissing the "Black Swan" actress under a neon sign which reads "SUN."

The two shared the sweet kiss in the dark. In the photo, the "Jupiter Ascending" star can be seen sporting messy bun hair. "Sunset #nofilter," Kutcher captioned the photo.

The pair, who have been dating since 2012, most-recently were seen together in the wedding of Kunis' brother at the Cathedral Church of Saint Peter in St. Petersburg, Fla. According to a source at the wedding, the pair looked "totally in love and inseparable" during the event.

"Mila was very happy for her brother and his wife. During the ceremony, she stood at the altar and seemed very focused on the vows," a source told E! News. "Every once in a while, [Mila] would look out to Ashton and make eye contact with him. Ashton was very supportive of Mila and happy for the family. He was joking around with Mila's brother and they invited him to come and pose for family pictures with the bride and groom after the wedding."

"They rarely left each other's sides and were always holding hands and whispering to one another. Ashton let Mila do her thing but always was right there at her side. If she was busy, he knew lots of people to talk to and was having a great time with her parents and friends," the source added.
