Olivia Munn and boyfriend Aaron Rodgers are already living a domestic bliss as the "X-Men: Apocalypse" star showed off her baking skills on Instagram.

A half-eated cake was posted on Olivia Munn's Instagram as the "Newsroom" actress baked her boyfriend Aaron Rodgers a dessert. She wrote, "I did it!! 3-layer white cake from scratch! #homemade #munnmade I read your comments on my last cake post and took all of your tips and tricks and it worked! This cake's for you e-boos."

One fan commented, "The cake top looks esp good with edging left plain. Munnderful!"

Another said, "Yummy looks like U did a wonderful job!!"

Later, she posted a cake now with a slice missing, probably eaten by boyfriend Aaron Rodgers.

In another post, Olivia Munn showed her support for her boyfriend's team, the Green Bay Packers, as she dressed their dog a green scarf showing the team's logo.

Aaron Rodgers previously told ESPN Radio that he's quite happy with how his relationship with Olivia Munn is going even if their private lives are put on the spotlight in the process.

"And I understand what comes with it. And two, the last couple years I've learned a lot about perspective and what's important," the quarterback said.

"And, that you cannot, when you've had success individually and collectively as a team and you are highlighted for the things you've done on the field and off the field, you cannot hide from the spotlight. You have to learn to embrace it."

Indeed, being a boyfriend to a celebrity means their private lives will be talked about at some point, including their sex routines for instance.

"The X-Men: Apocalypse" star was asked by Andy Cohen on "Watch What Happens Live" whether they have sex on game day.

"No, we don't. Not on game day," Olivia Munn said. "There's not a rule, but it just doesn't happen because there are other things to focus on."
