Lindsay Lohan and Samantha Ronson have reportedly solidified their relationship by getting matching black heart tattoos on their left hands.

The gal pals, who are rumoured to be dating, visited a West Hollywood tattoo parlour in June, and are believed to have had gone under the needle then, reports E!

Mean Girls star Lindsay originally had a loveheart tattoo done in white ink between her thumb and index finger in 2006, but recently outlined it in black. Her DJ ladyfriend matched the design on her left hand – Who needs commitment rings when you can have permanent scars?

In addition to the love hearts, LiLo also opted for a red star on her right hand, presumable to match the scattering of red stars Sam has on her right arm.

Let’s hope they won’t regret their decision.
