When Lily met Leo Lucky

Lily Allen not only lapped up the Cannes sunshine this week - but she got to spend some time with the hottest man on the planet - or we think he is. Look closer, it is none other than Leonardo Di Caprio. We are so jealous of her right now. And they are on a boat, we wonder if that is the first time 'Jack' has been on one since Titanic...

Excited much?

Radio 1 presenter Nick Grimshaw looks a wee bit too excited at that #weegiebigweekend has officially kicked off. The star posted this picture with Friday performer DJ Martin Garrix on his Instagram, and said a simple, "MOOORNING." They look like they are behaving like 'Animals' - sorry we couldn't resist.

Katy Perry is the new Simon Cowell

Sunday headliner Katy Perry seems to think she has the ability to see the X-Factor in fellow artists. The US singer predicted that singer Sam Smith, who is also performing at #weegiebigweekend is like the new Adele. Now that is a compliment if we have ever so.

Disturbing Cannes before Glasgow

Tinie Tempah was living it up in Cannes ahead of #weegiebigweekend - and we can only hope we get the same weather in Glasgow.

Learn all about it

Radio 1 DJ met up with Scottish singer Emeli Sande during academy sessions in the city. We wish she was performing.

More glamping than camping

Ladies we better rethink our #weegiebigweekend outfits if this is the sort of attire Rita Ora has been showing off this week. Now where did I put my Chanel wellies - we can only dream.

One way or another...

Harry Styles is on the move people...which means we are even closer to seeing One Direction on the #weegiebigweekend stage.

But first let me take a selfie...with a falcon

Ed Sheeran attempted to create a new selfie craze as he posed for a picture with a falcon. We don't quite get it but we prefer celebrity selfies - and the falcon isn't famous.

Calvin Harris - a pool player - who knew?

Kesha isn't a very good pool player according to Scots DJ Calvin Harris who posted this picture on Instagram. He said: "Just beat @iiswholis at pool convincingly 3-0 sorry luv." Not one to brag about it are you Calvin?
