The couple that goofs off together, stays together, right?

Joe Jonas and Sophie Turner are getting goofy.

The rumored love birds took to a friend’s wedding in Malibu and took full advantage of the event’s photo booth, sporting their best funny faces, Entertainment Tonight reports.

“About last night table 5 madness…,” Jonas’ brother, Nick, captioned an Instagram post of the photos.

In one section of the photo booth shot, Jonas, 27, and Turner, 20, donned wide, over-the-top grins. And in the other, the singer and Game of Thrones actress sported sinister, sultry smirks.

The pair fueled romance rumors earlier this month when they were seen getting cozy at a concert in Rotterdam, Netherlands.

A source told PEOPLE then that Turner “has had a crush on Joe for a while, but Joe isn’t going to be a one-woman guy right now.”

They later spent Thanksgiving weekend together, with a source previously telling PEOPLE that Jonas thinks Turner is “a cool girl.”

“She’s always been into him, but he’s starting to like her more and more,” the source said.

Jonas and Turner also got together for Halloween, with the DNCE frontman dressed as a dalmatian and Turner dressed as a bunny in a photo uploaded to Instagram.
