Lindsay & Sam are Bikini Babes

Bikini-clad Lindsay Lohan and Samantha Ronson soak up the sun, sea and sand while vacationing together in Mexico on Monday.

According to The Sun, Lindsay has included a disguised dedication to her DJ girlfriend on the CD sleeve of her upcoming album.

A source revealed: “Sam has had a huge influence on the record. The artwork was finalized before Lindsay had gone public with the relationship, so she concealed the tribute. Now it will name Samantha directly.”
