Looks like things are getting serious between everyone’s favorite lesbian couple — Samantha Ronson has finally proposed to girlfriend Lindsay Lohan! Well, sorta. According to The Mirror

Sam splashed out on an [$22,000] Cartier diamond ring for her girlfriend. “Sam took Lindsay shopping to celebrate her 22nd birthday,” says a source. “Although Lindsay is the major breadwinner, Sam has her own money and is very proud. It’s a token of her commitment. Lindsay is thrilled.”

Everyone agreed it was a real step up from the gold-plated dental dam Sam gave Lindsay last month, which was really less of a pledge of eternal love and more of a I-don’t-want-your-herpes-on-my-tongue kind of gift. Still nice, though! Congratulations to the happy couple!
