Ring on Her Finger!

We speculated that love birds saMAN Ronson and LezLo were ring shopping when they were spotted at an LA jewelry store last week, the day of Lohan’s birthday.

If the following report from Brit rag the Daily Mirror is true, then we were indeed on to something!

They’re claiming that saMANtha gifted LaLohan with a $22,000 Cartier commitment ring on her birthday.

An insider told the paper, “Sam took Lindsay shopping to celebrate her 22nd birthday. 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.”

And committed to each other, it seems.

Does commitment ban Lindsay from hooking up with random dudes? It’s just sex, right?
