NEW YORK (AFP) - Mariah Carey announced on Tuesday that she would star in a reality television series about her upcoming tour and marriage.

The pop diva known for her soaring five-octave range said the E! entertainment network would follow her for an eight-part series entitled Mariah's World. "Mariah is one of the most captivating pop superstars of our time and one of the rare artists whose first name alone is instantly recognised around the globe," Jeff Olde, the network's executive vice-president for programming and development, said in a statement.

The series will follow Carey as she plans her wedding to Australian casino tycoon James Packer and raises her twins from her previous marriage to TV host and actor Nick Cannon.

Mariah's World will also cover her tour of Europe and South Africa, which opened on Tuesday in Glasgow.

Carey was the top-selling female artist in the United States in the 1990s and her 1995 song One Sweet Day with Boyz II Men maintains the record for the most weeks at No.1 on the Billboard singles chart.

But her last album - 2014's Me. I Am Mariah... The Elusive Chanteuse - was her weakest chart performer. Last year, she began a residency show at Caesar's Palace in Las Vegas.
