According to an insider Sam Ronson gave Lindsay Lohan a Cartier diamond ring worth $22,000 for her birthday.

Britain’s Daily Mirror is reporting that a source told them,

‘Sam took Lindsay shopping as part of her birthday present. 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 content.’

So are they trying to say it’s a promise ring? Last time I checked an engagement ring and a commitment ring were the same thing. Anyway, I am sure that the ring will be a nice replacement for Lindsay’s tacky SR ring.

Tell me what you think–engaged or not?
