Jessica Simpson and her husband Eric Johnson are clearly massive fans of "Fifty Shades of Grey" -- and so they took the material to heart (and art!)

On Valentine's Day, Simpson posted some seriously racy photos of the couple in various rapturous poses, captioning them with the hashtag #FIFTYSHADESOFJOHNSON, and let's just say...they're giving Jamie Dornan and Dakota Johnson a serious run for their money.

Whoa. Everybody breathe in. Breathe out. Most amazing marriage ever? We would not be at all surprised if this whole thing culminates with an announcement for baby #3. Stay saucy, you sexy Simpson-Johnsons!
