Mariah Carey announced 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 that 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 recognized 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 the 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 upcoming tour of Europe and South Africa which was opening 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 number one 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.
