Here's some irony. Diane Kruger appears to be cheating on Joshua Jackson, a star of "The Affair" — with Norman Reedus of "The Walking Dead."
Multiple sources tell Confidenti@l that Kruger and Reedus were spotted wildly making out in an East Village dive bar early Saturday morning.
We're told the pair — who co-starred, along with Jackson, in this year's movie "Sky" — showed up at 12th Street Alehouse around 1:30 a.m.
We're told they ordered a vodka for her and a whisky for him and retreated to the very furthest table in the bar's back room.
"They were laughing and having fun and then she just literally got out of her chair and straddled him and we were all like, 'what the hell,'" said one stunned onlooker. "They were all over each other. She was a lot more aggressive than him."
Another eyewitness said, "they were making out on top of each other, holding hands."
Her long-term boyfriend, meanwhile, was on a beach on the other side of the world.
The "Dawson's Creek" hunk — who plays Cole Lockhart in Showtime hit "The Affair" — posted an Instagram shot on Friday of an idyllic beach in Manila captioned, "Home sweet home for the next couple days."
Jackson, conveniently for the hot and heavy Kruger and Reedus, is on a 21-day trip around the world.
Jackson and Kruger have been a Hollywood golden couple since they began dating back in 2006.
Last month he told People Magazine that the secret to the longevity of their relationship is that they, "work on it."
"I mean it's so banal. It's not always easy because nothing in life that's worth doing is always easy," he told the magazine. "I understand at 37 better than I ever did at any other time in my life what the phrase like, 'Love's labor' really means. It's work. But it's work that rewards itself many times over."
In 2007, the German actress told Us Weekly that they have never married because neither one of them is "particularly religious."
"Marriage is important for the people it's important for, but neither one of us is particularly religious, so I don't think there's any particular push," she said, "But never say never!"
A rep for Reedus denied that Reedus and Kruger were making out.
A rep for Kruger declined to comment. A rep for Jackson did not respond to our request for comment.
