The singer and actor sang tracks from the LP, which sees him covering Broadway love songs including A Chorus Line's 'What I Did For Love', and 'Raindrops Keep Fallin' on My Head' from Butch Cassidy and the Sundance Kid.
The star said: "I was really excited about this morning, I've been waiting for this for a long time."
Asked if he will ever be "a pipe and slippers guy", he insisted: "No never, I'm on the Hoff train, the Hoff train is smoking! When you go to a Hoff party and everyone's dressed as me, it's pretty wild."
On selling his album via the shopping channel, he insisted: "People such as Sheryl Crow go on QVC. I'm not expecting the album to be the top of the charts; I just wanted to make it. The songs really mean something to me."
QVC record sales became chart eligible in 2011, causing the likes of Charlotte Church, Westlife, Dolly Parton, John Barrowman and Peter Andre to use it as a promotional tool.
It was recently reported that Hasselhoff proposed to his girlfriend Haley Roberts on the Sydney Harbour bridge.
