This thong is certainly less than six degrees separate from Kevin Bacon

Bacon quite literally put wife Kyra Sedgwick’s dirty laundry on Instagram Sunday, posting a photo of a blue lace thong with "I [heart] KB" spelled out in crystals.

"Sometimes doing laundry can be fun and full of surprises," he wrote, snapping a photo of the personalized panties atop a washing machine. 

"Thanks for airing my dirty laundry," Sedgwick commented on her husband’s cheeky pic, prompting him to reply with a heart.

Followers were amused by the "Footloose" star’s snap, with many pointing out the reflection of Bacon’s face in the laundry knob, which one called "Artsy AF."

Others joked that the underwear could be a tribute to a different famous "KB," with one writing, "Ken Burns?" while another added, "I am a fan of Kim Basinger too."

The pair instead ended up in a sticky situation, which Bacon later called "really, frighteningly dangerous" despite him being "cocky enough to think [he] can probably learn to do anything."
