Pakistan, Feb. 26 -- Lady Gaga may have channeled her inner Judy Garland on the red carpet of Sunday's Academy Awards, but she resembled the late Audrey Hepburn with a dazzling $30 million diamond once worn by the iconic actress. Gaga paired the 128.54-carat Tiffany & Co. diamond - named the "Tiffany diamond" - with an Alexander McQueen gown.

She also picked up an Oscar for best original song for "Shallow" for the film "A Star is Born."

Sunday marked the third time the Tiffany diamond was worn and its first time on a red carpet.
