Beyoncé Knowles wowed fans by wearing a see-through leotard for the start of her world tour.

The 'Baby Boy' singer, who recently cancelled her Malaysia concerts after refusing to conform to the country's conservative dress code, donned a series of skimpy costumes, including a risqué leotard with strategically placed Swarovski crystals, for her Ethiopia show on Saturday.

Beyoncé told the 5,000 screaming fans: "I want to thank you. You have been one of the best audiences of my lifetime."

Ethiopian capital Addis Ababa welcomed Beyoncé's two-hour performance as part of the country's year-long celebration of its 2000th year, according to the Coptic calendar. Beyoncé's opening act, multi-platinum-selling rapper Ludacris, failed to impress the crowd. Local music promoter Michael Melake explained: "Rap music doesn't suit Ethiopia.

"Ethiopians need a melody. Rap music is all about the message and we don't identify with that. It's all about the black American experience, and we don't relate to that."

The Black Eyed Peas, who performed in Addis Ababa in September, also received a lukewarm reception.
