So... how did you spend your Valentine's Day?

If you ask Jessica Simpson, the "I Think I'm in Love with You" chanteuse spent it posting some steamy, "Fifty Shades of Grey"-inspired photos with her husband, former NFL tight end, Eric Johnson.

The singer put three sexy photos on her Instagram account Sunday, just two days after the film adaptation of E.L. James' novel hit theatres.

Simpson clearly thinks "Fifty Shades" is sexier than Madonna does.

The "Like a Virgin" singer has described the book as "pulp fiction" and is clearly unimpressed with its sexual content.

"I kept waiting for something exciting to happen in that red room thing, and I was like, 'Hmm, a lot of spanking,'" she told Billboard.
