Bruno Mars and Kendrick Lamar with Rihanna

Bruno Mars was the big winner at the Grammy Awards 2018.

The R&B artist won the top prize on Sunday, denying rappers Kendrick Lamar and Jay-Z the honour of becoming the first hip-hop artist in 14 years to win the coveted album of the year award.

Mars won six Grammys including song of the year for his hit single That's What I Like, and both record and album of the year for 24K Magic.

Lamar, 30, regarded as one of the most innovative rappers of his generation, won five prizes mostly in rap categories, for his album DAMN and single Humble.

Lamar's victories came at the expense of veteran Jay-Z and his soul-baring album 4:44. Jay-Z won none of his eight nominations and chose not to perform at the three-hour show.

Rap last year surpassed rock as the dominant genre in U.S. music.

On the red carpet, dozens of musicians wore or held white roses to signal support for women's equality and freedom from sexual harassment, a theme that was echoed on stage in an emotional performance by Kesha of her single "Praying."

Mars dedicated his award to songwriters Babyface, Teddy Riley, Jimmy Jam and Terry Lewis.
