Olivia Newton-John, the UK-born Australian singer who found worldwide fame in the hit movie Grease, was given a damehood in Britain's traditional New Year Honors unveiled on Friday.

The entertainer, whose career has spanned more than five decades, was joined on the prestigious annual achievement list by Oscar-winning Hollywood directors Sam Mendes and Steve McQueen.

English cricketing heroes Joe Root and Ben Stokes also received awards following the country's first Cricket World Cup victory last summer.

Queen Elizabeth II's New Year Honors List recognizes outstanding achievements in the worlds of showbiz, sport and politics, as well as the contributions of a larger number of everyday citizens.

Overall, 1,097 names were on the list for 2020, nearly two-thirds of whom have undertaken outstanding work in or for their local community.

Newton-John, who has devoted much of her time and celebrity to charities after battling three different cancer diagnoses since the early 1990s, said she was "extremely excited, honored and grateful" to receive the award.

"As a girl born in Cambridge, I am very proud of my British ancestry and so appreciative to be recognized in this way by the United Kingdom," she told Britain's Press Association.

The 71-year-old moved to Australia with her family when she was 5. 

Mendes, best known for his acclaimed directorial debut American Beauty, and McQueen, who made history in 2014 when he became the first black filmmaker to win a best picture Academy Award, both earned knighthoods.

Mendes, 54, the director of two Bond films, said he was "amazed, delighted and extremely proud."

"I have stood on the shoulders of so many collaborators and colleagues... to whom I owe a huge debt of gratitude," he said. 

"I would not be receiving this honor without them."

McQueen's biggest success was the 2013 biographical drama 12 Years A Slave - a searing portrayal of slavery in the US which proved a box-office hit. 

His most recent film is the crime heist drama, Widows, starring Viola Davis.

Elton John - who was knighted in 1998 - received an upgrade in this year's honors.

He was appointed to the Order of the Companions of Honor, awarded to people who have made a significant contribution in their field over a long period. Recipients carry the initials "CH" after their name.
