Margot Robbie shows off surprise skill on Graham Norton

Margot Robbie has won over UK TV viewers with an unexpected skill, after she tattooed a member of Graham Norton's talkshow staff live on-air.

"I'm not particularly good, but I like doing it!" the 27-year-old Gold Coast actress told the brave production staffer while inking his foot.

Robbie - who appeared on the show alongside all-stars Harrison Ford, Ryan Gosling and Reese Witherspoon - was promoting her new flick Goodbye Christopher Robin, where she plays Daphne de Selincourt, the wife of Winnie-the-Pooh creator AA Milne, when host Norton switched the conversation to her affinity for tattoos.

The host flashed an infamous Instagram pic of Robbie and Suicide Squad co-star Cara Delevigne showing off their "toemojis" - little faces they'd tattooed onto their toes while filming the blockbuster in 2016.

"I reckon I've done probably close to a hundred now," the actress revealed, adding, "Little ones... And honestly, I'm probably getting worse as I go along."

On cue, Norton ushered in a tattoo gun, and asked Robbie's couchmates whether they'd be keen on getting inked.

Ford feigned enthusiasm, while Gosling and Witherspoon instantly declined - leaving the slate clear for Norton's staffer, a big Robbie fan, to be the willing guinea pig.

"I'm sorry, I'm probably more nervous than you are..." Robbie said. "My hands are shaking, but you probably don't want to hear that."

A few seconds later, the damage was done.

"That's not bad!" Norton exclaimed.

Robbie has a string of films due for release in the coming months, including her critically-adored turn as disgraced figure skater Tonya Harding in I, Tonya in February.

The actress recently spoke out about her conflicted thoughts on the buzz, which has largely focused on her physical transformation - and its departure from the sultry bombshell she played in 2013 breakthrough The Wolf of Wall Street.

"All the reading, all the acting coaching, and then someone reviews the movie or interviews you and all they do is focus on the aesthetics," she told Wonderland magazine.

"You think, 'F--- you, you've totally discredited the work I did and it's not fair.'"
