"We never imagined at first that Naomi would wear this.

Julia Roberts sent out her own cryptic message in 2002, when she was eager to marry Danny Moder, and chose to walk around one spring day in a shirt that read, "A Low Vera." It was something she never cared to explain.

Perhaps the "Pretty Woman" was advocating the healing qualities of aloe vera — and she's merely a lousy speller. But many believe Roberts was sending a message to Moder's estranged wife, Vera, who was said to be stalling divorce proceedings.

When love goes awry, how can your average star resist not letting the world know? This is how everyone would communicate, if only the rest of the world cared what was written on the less-than-average person's shirt.

Last December, when reports surfaced that Lohan's ex-boyfriend, Wilmer Valderrama, was getting friendly with exotic dancers at a Los Angeles strip club, the "Mean Girls" star was soon seen in a T-shirt that read, "You Were Never My Boyfriend."

Valderrama has yet to be seen in clothing with a retaliatory message. But if he pulls on a snappy T, will it say "Feed Lindsay" … or simply "Fed Up With Lindsay"?
