Lindsay Lohan & Samantha Ronson Engaged?

For the next chapter in the Lindsay Lohan and Samantha Ronson fairytale look no further than Li-Lo's left hand.

Rumour has it that the loved-up pair are planning to tie the knot after the actress showed up to a party sporting a heart shaped diamond ring on her engagement finger.

The Mean Girl made sure the paps got an eye full of what can only be described as a rock big enough to sink the titanic on the red carpet at a Marie Claire party.

This comes only days after girlfriend Samantha announced at one of her gigs the couple would be married within the next six months.

Mother Dina Lohan stood by her daughters' side in firm approval of her intentions to marry into the Ronson clan.

While father Michael Lohan is no doubt ready to give the news a tongue lashing – begging the question who'll be giving his daughter away in six months?
