New York: Rihanna is now under Jay-Z`s umbrella.
The Grammy-winning pop singer has parted ways with manager Marc Jordan and is now being managed by Jay-Z`s Roc Nation Management.
Rihanna told The Associated Press in a statement Wednesday that she`s "so excited to take this next step in my career."
The 22-year-old is also launching a new company called Rihanna Entertainment. She says it will "merge all of her businesses, including music, film, fragrance fashion and book ventures."
Jay-Z signed Rihanna to Def Jam in 2005. The two won a Grammy in 2008 for the hit song "Umbrella." Earlier this year, the pair picked up two Grammys for the rap song "Run This Town," which also featured Kanye West.
She`s released four albums and plans to release her fifth CD, "Loud," on Nov. 16.
