Former Italian premier Silvio Berlusconi is reviving his musical career, just a week out of office.

The billionaire media mogul released a new CD with musical collaborator Mariano Apicella.

Berlusconi - a one-time cruise ship crooner - does not sing on the new collection, titled "True Love," but co-wrote all 11 songs.

The album features love songs and jazz arrangements. It is the fourth CD that Berlusconi and Apicella, a Neapolitan guitarist and singer, have recorded together.

It's too early to say how sales are going.

Mr Berlusconi resigned on November 12 after failing to come up with economic reforms that could persuade markets and European partners that Italy could escape the continent's debt crisis.

The twice-married ex-premier has often boasted of his prowess with women. Parties at his residences attended by attractive young women have landed in him trouble with prosecutors, who have charged him with allegedly having paid for sex with an underage Moroccan teenager and using his influence to cover it up. The trial is under way in Milan.
