Call her the Maternal Girl: Madonna is four months pregnant with her first child.
The 37-year-old singer, now in Budapest filming a movie version of the hit stage musical "Evita," is "deliriously happy," publicist Liz Rosenberg told Britain's GMTV."This is the greatest and happiest surprise in her life," said a statement by her press office.
The baby's father, Carlos Leon, a 29-year-old fitness instructor, was also said to be pleased by the news.
The London tabloid the Sun cited an unidentified source close to the singer as saying: "She has no plans to marry Carlos, but he is totally supportive."
"She has always wanted to have children," Rosenberg said. "She has spoken about it quite frankly over the last year or so, but it was not something she was particularly planning. She wanted to finish filming, but nature took its course."
Madonna, whose hits include "Like a Virgin" and "Papa Don't Preach," has had several failed relationships, including one with film star Warren Beatty. Her four-year marriage to actor Sean Penn ended in divorce in 1989. The Sun said Leon had been her lover for more than a year.
The press statement said Madonna's pregnancy will not affect the "Evita" filming schedule.
