PRAGUE - AUSTRALIAN actress turned pop diva Kylie Minogue will announce her marriage to French actor Olivier Martinez at a concert on May 12, a Czech website said on Thursday.

Minogue, who turns 40 in May, will announce the marriage in Prague, Czech organiser Jarda Hainzel was quoted as saying in the website www.idnes.cz, adding that the number 'of VIP tickets demanded by Kylie's team for the show surpassed the usual number.'

Minogue launched her singing career in 1987 with the album 'Locomotion', which sold 14 million copies.

In 2006 she was forced to cancel her 'Showgirl' tour due to breast cancer, making a comeback after her recovery.

Her European tour Kylie X2008 kicks off in Paris on May 6 and wraps up in London on July 27.
