'It's pretty big, it's on his arm': Margot Robbie admits to mistakenly spelling the word 'skwad' as 'swad' as she tattooed the arm of film assistant on Suicide Squad

She is set to play a villainous siren in the upcoming flick Suicide Squad. 

But between the sets, actress Margot Robbie, 25, played the role of ink-master by offering free tattoos for all her fellow castmates, while leaving one unlucky victim with a misspelled etching.

'I did spell one wrong once on an epic dude named Simon, who was Jai Courtney's cast assistant,' Margot chuckled while appearing alongside Tina Fey on Sunday night's edition of The Late Show with Stephen Colbert.

The Australian actress explained that she acquired a tattoo gun while filming, and decided to put her artistic skills to the test by inking as many people on set as possible with the word 'SKWAD'.

'He put his hand up first to get the 'skwad' tattoo', she said of Simon. 

She continued, 'It's pretty big, it's on his arm. Everyone was spelling it 'SKWAD', and I went straight from the 's' to the 'W', so it read 'SWAD'.
