On Saturday, Simpson posted a Twitpic of herself in a liplock with the Yale grad and former San Francisco 49er, with a caption reading, "Romance 101..getting kissed by my Yalie...me not lookin' so smart...:) but YUM!"
This isn't the first time Simpson and Johnson, who have reportedly been dating since May, have engaged in a little public affection.
In July, an eyewitness at a Florida airport told People the pair, both 30, were getting "huggy-kissy" at the ticket counter, and the couple was also caught doing some serious smooching while on vacation in Capri.
Not surprisingly, the divorced singer said she is optimistic about finding love again. "It's happening and I feel it," she said in May. "I think  is going to be a good year for me."
