Samantha Ronson and Lindsay Lohan were rumored to exchange a commitment ring a few weeks ago but now according to Life & Style Weekly the two gal pals have reportedly exchanged more comitment jewelry.

Lindsay and Sam have been wearing matching Jules Smith Infinity Lock bracelets. "The bracelets represent their relationship -- they have each other on lockdown, and there's no one else who can open up the key to their hearts."

Now I have no idea what this "Infinity Bracelet" looks like (Google doesn't either) but Sam and Lindsay have been spotted all over New York wearing the same bracelet. In the picture above they are both wearing the same red bracelet and peep the picture below to see the matching gold bracelets they've also been sporting.

Eh, my guy friends and I all have matching jockstraps that we break out at our "wrestling parties" so all this matching jewelry could just be a friendship thing but all bets are off if SamRo steps out in a pair of leggings from Lindsay's line.
