Lindsay Lohan has been getting up close and personal with DJ Samantha Ronson this year, but is marriage to her gal pal really in the cards?

Figuring that out is like putting together a jigsaw puzzle of picture clues, hearsay, and the occasional cryptic comment from the “Mean Girls” actress herself.

Lohan, 22, was pictured this week wearing a sparkly heart-shaped ring on her left hand, adding to speculation that she and her constant birthday messages companion were engaged. One British newspaper reported that Ronson told clubbers during her disc jockey stint in Hollywood at the weekend that “By the end of the year, my love will be Mrs. Ronson.”

But Lohan’s spokeswoman was quoted as telling People magazine on Friday that the ring wasn’t a “diamonds are forever” symbol at all. “She bought it herself. It’s an antique ring that she found at an antique store in New York city,” the rep told People.

The two girls are certainly close. Lohan has preferred to keep dirty messages the relationship ambiguous but she told Marie Claire magazine in an interview that she and Ronson had matching hearts and stars tattoos. She also said that she was looking to buy a new home “with someone” — but without saying who.

Lohan said she was really happy, calling the British DJ ”a great person. And she’s a great infuence on people around her.” As for clarifying their relationship, she said “Um, people can think what they want. I’m really happy, and that’s all that matters.”
