I’m not sure if Dina Lohan could have asked for a better way to promote her new reality show…

Although most people have already assumed Lindsay Lohan and her gal pal, Samantha Ronson, were more than just friends, the buzz around the twosome has grown within the past week.

Last Thursday, the two made a very public statement when they were seen kissing at the Cannes Film Festival. (I have no idea what Lindsay was there to promote.) While partying on Diddy’s yacht (I don’t think he had anything to plug either), the ladies let their affection for each other be known - and they didn’t care who saw it. And since the 21-year-old actress is supposed to be laying off the sauce, the smooches and hand-holding weren’t things that could be blamed on alcohol later.

While it’s unclear whether Mama Lohan will address her first daughter’s relationship on Living Lohan (the E! program debuts tonight), she has already given the 30-year-old DJ her stamp of approval. That’s a good thing - because if the latest rumors are true, Lindsay’s not only got a new roommate, she’s got a new fiancee as well.

Let’s see if Dina still thinks Samantha’s a “sweetheart” then.
