Lindsay Lohan and DJ Ronson has taken their relationship one step further as she was gifted a $22k ring from her openly gay gal-pal.

Samantha Ronson splurged the huge amount of a Cartier diamond ring for LILO’s 22nd birthday.

A source close to the lesbian couple says,  “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.”

Lohan was later snapped wearing the ring when she was shopping with girlfriend Ronson.

So when is Samantha gifting LILO an engagement ring?
