Rihanna's upcoming album and tour will be sponsored by South Korean electronics giant Samsung for a deal worth $25 million, reports The Post.

Rihanna, known for hit songs such as 'Umbrella' and 'Rude Boy,' is signed to Roc Nation, run by rap mogul Jay Z, who has had a long and profitable relationship with Samsung.

According to reports, the singer's new deal follows seven months of talks and is the biggest music-marketing tie-up in recent memory.

"Hammering out the details took longer than expected in part because Rihanna made some last-minute tweaks to the album," a source said.
