LiLo's Diamond Promise Ring

Are they or aren't they? One of the great questions plaguing modern civilisation. Nope, it's nothing to do with the price of oil, Middle-Eastern conflict or global warming, according to the amount of press coverage - most Americans are truly considered with knowing whether Lindsay Lohan is involved with DJ Samantha Ronson. Now more fuel has been added to the love tryst rumours. Samantha has allegedly bought her actress girlfriend a $22,000 Carter diamond ring.

The ring is apparently a 'promise ring' for Lohan's 22nd birthday - a token of Ronson's 'commitment' to Lilo.

According to a British tabloid, Lindsay, whose partying ways have been curbed by Sam, is said to be “thrilled".

Now, back to global warming......
