You could see this one coming from a mile off!

David Gest has dissed ex-wife Liza Minnelli while making his debut as a singer -- with a Scottish rock band.

Gest recorded a verse for the new single from Attic Lights -- set to be the next big thing to come out of Scotland -- after meeting their manager on a flight from London to Glasgow.

The TV exec, who split from the Cabaret star in 2003 after a stormy 18 month marriage, then joined his new friend to party with the indie five piece.

And when he heard their new single, Bring Me Down, Gest penned a verse, apparently about Minnelli, then raced to a recording studio at 3am to record it!

"They broke the rules when they made you," he spits on the song, "who would ever think a love so bold would find a woman so cold!

"When I looked into your past, I knew it would never last."

Sounds like someone's still a little bitter after all these years!
