British pop singer George Michael and long-time boyfriend Kenny Goss have split.

Michael announced the break up during an emotional performance on Monday at the opulent Prague State Opera, the Reuters news service reported.

The singer shared with the audience that he and Goss separated two-and-a-half years ago. He said Goss' struggles with alcohol had driven a wedge between the pair.

“My battles with substances are well documented and my partner went through similar problems with drink,” Michael told the audience.

Michael most recently pleaded guilty to driving under the influence of drugs during a July 4 car accident, in which he crashed his Range Rover into a Snappy Snaps 1 hour photo shop in north London. He was given an 8-week jail sentence and fined nearly $2,000 in September.

“The truth is my love life has been a lot more turbulent than I have let on,” he added during the introduction of his new track Where I Hope You Are, which he said was inspired by the split. “This is probably the first break-up song I've written.”

Monday's performance was the first of 195 concerts on his recently announced Symphonica tour, which pairs the former Wham! singer with prominent orchestras. With the accompaniment of the Czech National Symphony, Michael paid tribute to the late Amy Winehouse, singing a cover of her trademark track Love is a Losing Game.
