Emma Watson has joked she needs a tattoo proof reader after her temporary Oscars inking had a grammatical error.

The 27-year-old's right arm featured a tribute to the Time's Up movement, which is helping to fight sexual harassment in the film industry.

But fans were quick to point out a grammatical error, with the tattoo missing an apostrophe.

The actress wrote on Twitter: "Fake tattoo proofreading position available. Experience with apostrophes a must."

The actress showed off the new tattoo on her way to the Vanity Fair Oscar party on Sunday.

It's a reference to the Hollywood campaign which is described as a "unified call for change from women in entertainment for women everywhere".

Instead of saying "Time's Up" the tattoo says "Times Up".

People were quick to volunteer themselves for the job.

While others pointed out the hashtag for #TimesUp doesn't actually have an apostrophe, with Twitter hashtags not supporting punctuation.

Emma has been at the forefront of the Time's Up movement - and recently donated £1m to another anti-harassment campaign.

In one of several posts on Instagram she said: "United across industries and communities, we believe all women and people deserve to live with safety and dignity. #TIMESUP on imbalance of power."

It's not the first time that fashion and activism have met.

Earlier this year at the Golden Globes stars wore black on the red carpet to show their support for #TimesUp.

And just last month, stars at the Brit Awards carried white roses.

People opted not to wear black at last night's Oscars ceremony though, instead wearing colours of their choice.
