Lindsay Lohan was a bit agitated on the set of her new movie Labor Pains yesterday after word leaked that her gal pal, Samantha Ronson, had purchased a $22,000 diamond Cartier ring for her. Even though Lindsay has no come out and confirmed she is involved with Same she has said their is someone special in her life and since the only person has has been with in months is Sam you can draw some conclusion. According to reports form the set Lindsay was frantically calling and texting Sam about the ring. Could this spell trouble or the pair??? I guess only time will tell.
