It might be hard out here for some, but looking at Lily Allen’s Instagram page it all seemed like one very fun filled Big Weekend for the 'Sheezus' singer.

Lily returned to Radio One’s Big Weekend this Saturday in Glasgow performing on the main stage after a five year absence from the festival. From the looks of things, Lily had a great time catching up with old friends and even making a few new ones. When she wasn't treating fans to songs form her latest album, she was treating them to some star studded snaps via her always entertaining Instagram page.

First up for the close up was One Directioner Harry Styles, Lily Instagramed a pic of herself and the heartthrob backstage with the caption “Lolz”, later tweeting “Just saw Harry Styles having hair extensions put in #exclusive.” We’re guessing these two enjoy a bit of friendly banter, either that or we’ll have to go back and study every single Harry hair pic since 2012.

She then found herself looking ecstatic with ‘Happy’ singer Pharrell Williams who was also playing on the main stage. Next up was a video of friends Nick Grimshaw and Rita Ora, where Nick ate some wotsits and Rita showed off her new colourful dreads for the occasion.

Lily then bumped into Coldplay singer Chris Martin who looked a little overdressed for the weather, but happy to see her. Later she planted a kiss on the cheek of songstress Katy B who had performed on the In Music We Trust Stage.

When she wasn't getting snap happy, Lily performed on stage wearing a metallic corset and green polka dot mini skirt. She had her hair tied up with pink extensions which were teamed with a pair of cool matching tinted sunglasses with winged edges.

Lily has certainly been giving all other celebrity Instagrams a run for their money as of late. Recently she’s posted pictures with Kylie Minogue, Kim Kardashian and Kanye West. But the best of all came when she snapped herself on a boat with Leonardo DiCaprio in Cannes and tagging it #rose #jack #topoftheworld. Keep up the good work Lily, we're following you!
