Exhausted from shopping on Robertson Boulevard in L.A. on May 9, Lindsay Lohan took a break to grab lunch at Cuvée Café when fans started shouting, "Courtney! Courtney!"

Lindsay Lohan looks like Courtney Love?

"People actually mistook Lindsay for Courtney Love!" a source tells Star.

Wearing black Ray-Ban sunglasses and bright-pink lipstick similar to what Courtney sometimes wears, she was a dead ringer for the rock queen.

"She was also looking extremely pale," the source adds. "You know things are going downhill when you get mistaken for an ex-druggie plastic surgery disaster who's twice your age!"
