Monaco boss Claudio Ranieri showed his players a video of Liverpool's first-half destruction of Arsenal before Sunday's showdown of the mega-rich French clubs but it failed to inspire a demolition job on the French Riviera.
Yohan Cabaye, signed from Newcastle last month, was again on the PSG bench and watched Javier Pastore put the visitors ahead in the eighth minute when he reacted quickly at the far post to an Alex flick on and headed home from close range.
Prince Albert of Monaco and his wife Princess Charlene made a quick dash from watching the Winter Olympics in Sochi, Russia to attend the game and saw Dimitar Berbatov come on as a second-half substitute to make his debut before Ranieri's side grabbed a late equaliser through Thiago Silva's own goal.
Silva lunged to keep out a cross from right back Fabinho and the ball looped past goalkeeper Salvatore Sirigu in the 74th.
The draw means that PSG maintains their five-point lead over second-place Monaco with 14 matches remaining.
