And it’s because the blonde actress was spotted wearing a ring of diamonds on her left ring finger while lunching with Samantha Ronson recently at Tuscan eatery E. Baldi in Beverly Hills! According to a friend close to the couple, “Sam and Lindsay Lohan are unbelievably happy and in a healthy relationship. And like any couple in love, they speak about marriage and the future, but right now, there is no wedding planned.” Lindsay Lohan’s rep did not comment on the ring while the pal said LiLo probably wore the sparkler to create “some more buzz.” LOL! And buzz for what?? Is she or Sam coming our with a new project soon?? As with regards to her relationship with Samantha Ronson, Lindsay Lohan has told Harper’s Bazaar in an e-mail: “I love the Ronsons. They’re close to my [heart] and I respect all the work they do. Samantha and my relationship is a private matter.” Private indeed! Tsk!
