Emma Watson has shown a permanent commitment to the Time's Up movement as she debuted a tattoo with the words at the Oscars.

But people were quick to notice that the actress and UN ambassador was missing a vital punctuation mark from the inking – an apostrophe.

Instead of reading "Time's Up", Watson's tattoo says "Times Up”.

Some have questioned whether the tattoo is real, or simply a temporary piece to make a statement.

Others backed her decision to get rid of the apostrophe, with one tweeter suggesting it would look "weird just floating there".

The apostrophe is also missing from the movement's hashtag on social media, as they do not yet support punctuation marks. Responding to the comments flooding social media on Monday, Emma eventually took to Twitter to address the mistake. "Fake tattoo proofreading position available. Experience with apostrophes a must," Emma wrote.
