The flamboyant Grace Kelly singer was at Somerset House for frolicking fun
Pop favourite Mika asked concert-goers here on the Strand to make an effort and wear crazy fancy dress for this sold out gig.
The costumes, including a Goldilocks and a cat, not only helped the atmosphere but also left Mika wondering how people managed to get on the tube dressed like that!
He put on a tremendous show with loads of theatrical effects thrown in while the Lebanese star also mentioned hed been touring for so long he could identify some of the audience.
The two most popular tracks with everybody singing along were singles Grace Kelly and a great extended version of Love Today. On Big Girls the Life In Cartoon Motion singer was joined by the songs subject in blue corsets.
Masked Mika thanked the crowd endlessly and dedicated his encore to everybody who had made an effort to dress fancy.
The end was quite a party scene with bubbles and confetti flowing over the audience and a chicken, dog and rabbit on stage.
Opening act Patrick Wolf is also worth a mention as he set the ball rolling with his twisted anthems and swooning string section.
