Jessica Simpson is clearly smitten with her boyfriend of three months. How can we be so sure?

The washed-up singer told us herself, Tweeting about former tight end Eric Johnson over the weekend: "I met a wonderful man,. Damn I'm lucky!" She then sent out her second photo of the pair, as seen here:

Jessica Simpson is all aTwitter over Eric Johnson.

Simpson, of course, has gone the NFL route before, having dated Tony Romo in a much-publicized relationship. She also let reality TV cameras film her failed marriage to Nick Lachey.

But sister Ashlee Simpson-Wentz makes it sound like Jessica has learned from these past mistakes.

Speaking on her sibling and Johnson, Ashlee said in July: "She is happy, so we are all really happy. Her happiness is the most important thing to me."

The same can be said for fans across the nation. Well, her happiness and the state of her body, that is.
