Bruno Mars

Eleven-time Grammy winner Mars, who has twice featured in Super Bowl half-time shows, will perform his 24K Magic World show on Saturday night in Texas, following qualifying for the 18th race of the Formula One season.

Spears, another international pop icon, will close out the weekend with a post-race concert on Sunday.

Bobby Epstein, the founder and chairman of COTA, said the performances of Mars and Spears would contribute to "an incredible weekend for race and music fans alike".

Mars provided the night's big upset, taking the album of the year trophy that most critics assumed would go to Lamar's rap tour de force, Damn.

In the end, voters found Mars's crowd-pleasing R&B more palatable, while Lamar dominated the rap categories.

Alessia Cara won best new artist - making her the only female artist to win a major prize.

Stars like Lady Gaga, Kesha, Lorde and SZA were overlooked, with only 17 awards (out of a total of 86) going to women or female-fronted bands.
