Lindsay Lohan's mother and sister have laughed off reports the actress is gay, insisting the rumour is just the latest in the long line of silly stories the press fire at the family.

The Mean Girls star has been linked romantically to pal Samantha Ronson for some time and now Dina and Ali Lohan are speaking out about the lesbian gossip.

In an interview to promote her new reality show, Living Lohan, Dina tells TV show Extra, "Samantha's an amazing girl," while Ali adds, "They're best friends. They're just friends. It's pathetic what people say."

Dina explains, "It's so silly. We actually laugh about it now. It really does hurt... but you develop a thick skin. You have to ignore it."

The interview ended abruptly when Extra reporter A.j. Calloway asked Dina about her relationship with her estranged husband - and Lindsay's father - Michael. The family publicist objected to the personal question and ended the chat.
