She has sold her fair share of albums over the years and can surely afford a chaffeur-driven car.

But Lily Allen chose a more down-to-earth mode of transport as she headed to the Beyoncé gig at London's O2 Arena - choosing to travel by tube to the venue.

Lily posted a series of pictures on her Instagram page of herself on the train, clearly thoroughly enjoying the novelty of travelling via public transport.

Standing out from the crowds, Lily opted for a green bodycon dress teamed with J Brand’s Aiah Leather Jacket in a bright pink Hibiscus shade.

Standing out: Lily completed her look with a clutch bag and metallic white Christian Louboutin heels

She completed her look with a pink floral headband in her hair, and white metallic heels.

However, the most successful accessory Lily wore for the night out was the gold belt which read 'Yonce' - which hung low on the mother-of-two's hips.

Clearly enjoying her time at the show, Lily also posted a shot of herself dancing to Beyoncé's performances as she watched from a box, hosted by Pandora jewellery, inside the venue.

Following the show, Lily kept the evening going by visiting the Groucho members club alongside friends including designer Henry Holland.

Lily's outing came after she opened up about the differences between men and women in a new interview with ShortList magazine.

She said: 'I like that when my husband gets up in the morning he spends about 12 seconds looking in the mirror then leaves.

'I’m not into men who are vain or even wearing aftershave. It gives me shivers. Men should be men. Go out, earn some money, come back and look after my children.'
