Shelley in a 1979 promo pic
Shelley became Charlie's Angel no. 5 in 1979 when she joined the cast of the hit TV series. Her character was Tiffany Welles and she took over the spot left open by Kate Jackson who played Sabrina Duncan for 3 seasons. It was reported that Kate made twice as much as Farrah Fawcett and Jaclyn Smith did during the 1st season of the show - $10,000 to their $5,00 per episode. The numbers must have changed during the second season as the series became a worldwide phenomenon. Shelley was reported to have made $10,000 per episode when she joined the series - which would have been increased to $15,000 if she stayed for another season. Not really that much when compared to the money she was making as THE Charlie Girl.
