Lindsay Lohan and Samantha Ronson are rumoured to have exchanged infinity bracelets as a sign of their commitment to each other.

The couple have never confirmed their romance in public but have chosen instead to let their increasingly brazen public displays of affection speak for itself.

And it seems that their feelings for each other are so strong that a simple promise ring won't do.

Instead they are reportedly wearing matching red infinity 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," a source tells Life & Style.
