According to the UK Mirror, Sam Ronson gave girlfriend Lindsay Lohan quite the little gifty! Check it:

Hip-hop DJ Sam — whose bro is producer Mark — has splashed out on an £11,000 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 not an engagement ring — simply a token of her commitment.

“Lindsay is thrilled and she and Sam are very content.”

I suppose ANY doubt that these two are an item can be squashed already? Now, will they be married before Ellen DeGeneres and Portia De Rossi (scheduled to wed this Fall?)….
