‘Tis the season for giving!

In a photo shared to Instagram on Friday, Shepard and Kutcher proudly held up a shower curtain with a giant photo of Kunis and her husband’s smiling faces on it.

“What a generous Christmas gift from the Kunis-Kutcher family,” Shepard, 43, jokinglycaptioned the shot. “A beautiful shower curtain for the attic(t) bathroom!”

The curtain is actually an inside joke between the couples as both Kutcher and Kunis have appeared on Shepard’s podcast,Armchair Expert,which is recorded in an attic above Shepard’s garage. In the attic, there is a bathroom which does not have a door, but that didn’t stop Kunis from using it.

“I look forward to her next one. Fingers crossed it’s about my #1,Brad Pitt:)” he jokingly concluded.

Edwards toldDaily Mailthat she “came forward” with the allegation “to get ahead of the story. I posted a photo on Facebook of me and Dax from that night as a joke and recently a few media outlets have contacted me about it.”

She later added, “I don’t want anything to do with Dax. I wish him well. I wish them to be happy. I hope that they’re happily married. I mean they have children. So my wish is that they’re happy and stable for the kids.”
