Singer Lady Gaga has praised Lindsay Lohan’s performance in “Liz & Dick”, a biographical TV film on Elizabeth Taylor. Directed by Lloyd Kramer, “Liz & Dick” was aired here Sunday. According to contactmusic.com, Lohan, 26, has received mixed reviews for her performance in the movie, including lots of negative feedback from her Hollywood peers. “You did a beautiful job on ‘Liz & Dick’. Let no one bring you down. Liz did not. They always try to knock the greats down a few pegs,” Gaga tweeted Monday. Lohan and Gaga have been good friends for some time and enjoyed a slumber party with singer Lana Del Rey at the Chateau Marmont in July.
