Kaley, 33, was all about a sexy photoshoot of her and her man.
She shared the selfie where both of them appear naked on Instagram. "I thought this picture was so sexy until @mrtankcook said we looked like siblings. Moment over. ?," she wrote.
The couple has been married since June 2018.
It's not the first racy pic the Big Bang Theory star has posted!
