Lily Allen had her first hangover in a ''long time'' after going out to celebrate her 27th birthday.

The 'Not Fair' singer enjoyed a night out in London last night (03.04.12) with a group of friends, including TV presenter Miquita Oliver, and she admitted they got a bit carried away with the alcohol.

Lily - who has a five-month-old daughter, Ethel Mary, with husband Sam Cooper - tweeted: 'Omg, first real hangover in a long time, not lol. (sic)''

She then hinted at what they had consumed by writing: ''Margheritas , margheritas , margheritas. (sic)''

Lily - whose actual birthday was on Tuesday (02.05.12) - looked lovely in a pretty flowery dress, black tights and heels, which she teamed with a black coat.

The group stayed out until 4am this morning (03.04.12) and Lily was assisted by Miquita as she left exclusive nightclub The Box.

As well as going out with her pals, Lily was thrilled when she got given a Lego plane for her birthday.

The 'Smile' hitmaker was delighted when she received a box of The Tiny plastic bricks which you turn into a miniature replica private jet.

She tweeted on Wednesday: ''This 'Backstage at the soap awards' thing has been the highlight of my birthday. That and the private jet obvs (sic)''
