The Harry Potter star kicked off the Easter weekend with a spot of club-hopping at her favourite haunts.
After spending the night partying at Whisky Mist in Mayfair and Bungalow 8 in nearby Covent Garden, a dishevelled Emma staggered home at 2.30am.
Wearing a chic black and white t-shirt dress and black heels, Emma looked younger than her 18 years with her natural look make-up.

She started the evening off at Nick House's Whisky Mist venue, where she has been frequently spotted partying over the last few months, before attending a friend's birthday at Bungalow 8, Peaches and Pixie Geldof's favourite club.
When she finally left at 2.30am, she was wrapped up in a coat and scarf with her formerly pristine hair hanging in front of her face.
Since turning 18 last April, Emma has become a regular on the London party scene, as well as becoming a popular celebrity in the front row of fashion shows in the capital and across the channel in Paris.
Despite her newfound social status and nights out at top London clubs, Emma insisted she's no party girl.
She told the Mail on Sunday's Live magazine: 'I’m not tempted by parties or drugs. I don’t actually like being drunk, particularly in public.

Her choice of short dress last night contradicted a recent claim by Emma that she'd 'never go out in a mini-skirt'.
Since becoming an official adult, Emma has been reluctant to see herself painted as a sex symbol in the media.
She said: 'I know everyone wants a picture of me in a miniskirt.
'But that's not me. It's nothing to do with protecting the Hermione image. I'd never go out in a miniskirt.'
Emma is currently taking time out of education after completing her A levels last year and is hoping to go university in the near future.
She said: 'I actually think going to university will make me a better actress.
'The experience of living like that, working to deadlines, living with other students. It’s all the things I want.
'There are actresses who don’t know about things like doing their own laundry and getting a bus. I’m not going to be like that.'
Meanwhile, Emma has reportedly been approached by Greenpeace to become an ambassador for the environmental charity.
A Greenpeace spokesman said: 'Emma would be perfect for us. She's posh, pretty, brainy and committed. She's also not too star struck to care if it's seen as vaguely controversial. She would really help.'
Emma will next to be seen playing Hermione Granger in Harry Potter and the Half-Blood Prince in July.
