Andrew Alcott Hallett (August 4, 1975 – March 29, 2009)[1] was an American actor and singer who became known from playing the part of Lorne in the television series Angel (2000–2004).

He eventually became a personal assistant to Kai Cole, wife of Buffy the Vampire Slayer creator Joss Whedon.

Kings" lounge at Universal CityWalk, Whedon conceived a new character for his new show Angel: Lorne, an anagogic demon who reads the hearts and futures of his guests as they sing in his karaoke bar.

According to a 2005 interview, about a month after filming the last episode of Angel, Hallett suffered a dental infection which spread through the bloodstream to his heart, leading to a case of cardiomyopathy, for which he spent five days in the hospital.

He did not return to acting (except for a voice part in the animated film Geppetto's Secret), but pursued his music career and frequently appeared at media conventions for Buffy and Angel and for science fiction and fantasy in general.
