Kiwi popstar Lorde says that although she's not the sporty type, she's "pretty proud" of the All Blacks after their world cup win.

First Bieber, now Lorde.

It seems celebrity pop icons can't help celebrating the All Blacks' win.

Kiwi pop singer Lorde was the latest star to jump on the All Blacks bandwagon after their victory over Australia in the 2015 Rugby World Cup final.

She took to Twitter on Sunday afternoon to express her admiration for the boys in black, saying: "all my life i've been a fervently non-sport 'forgot my p.e gear' type gal but jeez i am pretty proud of the @AllBlacks rn [sic]".

According to mum Sonja Yelich's Instagram, the 18-year-old pop sensation and her were on a long-haul flight while the game was on. Their Air New Zealand cabin crew kept the passengers up with the score, and played Queen's We Are the Champions over the plane's loudspeakers when the victory was announced.

This was not the first time Lorde has come out backing the All Blacks this year.

She also took part in a humorous charity single supporting the team, which was released in September.

The song, Team Ball Player Thing, featured numerous other New Zealand musicians including Jemaine Clement, Jordan Luck and Savage.
