Rapping in perfect Hermione! 'Embarrassed' Emma Watson beatboxes for the first time as she joins forces with Hamilton star Lin-Manuel Miranda 

Emma Watson proved that she is willing to do almost anything to get the word out about gender equality. 

And that includes a very awkward attempt at beatboxing in time for Hamilton creator Lin-Manuel Miranda as he rapped about feminism for International Women's Day.  

Launching into a somewhat cringeworthy effort, the 25-year-old British actress was left mortified with embarrassment afterwards, despite giving it her all. 

Indeed, the bashful Watson turned red following the brief performance, describing herself as 'literally the color of a tomato'.

First time's a charm: Emma Watson attempted to beatbox as lyricist and actor Lin-Manuel Miranda rapped about feminism for International Women's Day

However, as the Harry Potter star had never attempted to lay down a beat before - she had to get a quick lesson from Lin-Manuel before embarking on the musical endeavor.

The duo began with some fun banter as Lin-Manuel, 36, introduced Emma as a 'great beatboxer'. 

'He's lying,' the actress whispered to the camera as she explained she had never tried it before.

But the rapper insisted that he was 'happy to freestyle if you beat box' in order to promote awareness about gender equality.

In jest: The duo began with some fun banter as Lin-Manuel, 36, introduced Emma as a 'great beatboxer'.

Lin-Manuel went on to ask if Emma and her Harry Potter co-stars ever beatboxed on set of the film series. 

'English school kids,' Emma said humorously, 'that's what we do all the time... beat box.'

The duo then explained that the video was for the He For She programme on International Women's Day, which took place on March 8.  

No excuse! 'English school kids,' Emma said humorously, 'that's what we do all the time... beat box.'

The rapper then kicked off with a freestyle rhyme: 'Yo it's Lin and I have to laugh because we are all half.'

'Women are half of the people on Earth / And yes, they should've been equal since birth,' he went on to explain. 

After they finished, Emma shrieked: 'I am so embarrassed right now!'

She added in horror: 'I am literally the colour of a tomato!'

After their debut musical collaboration, the pair then attempted to sort the Hamilton characters into Hogwarts houses.

'Because obviously I’m Hermione, I had to plan this out,' said Watson. 'I have it on paper.'

Watson then put Alexander Hamilton into Gryffindor, but Miranda then revealed that when he asked Daniel Radcliffe the same question he put the US politican into Ravenclaw.

'I'm going to have to call him about this,' said Watson.

Miranda is having quite the week.

On Monday, the 'Hamilton' creator, writer and star freestyle rapped with President Obama at the White House, setting social media alight.

Lin-Manuel's freestyle skills have been showcased on Jimmy Fallon's late night show, but this time he put them to the test in front of the President
