Singer Idina Menzel was left out in the cold on Sunday (07Oct12) after she was turned away from her own rehearsal in London.

The Tony Award-winning Broadway star is in the U.K. for a solo concert tour, which kicks off on Monday (08Oct12) with seven consecutive performances scheduled at the Apollo Theatre in the British capital.

The Glee actress admits she had a "very humbling" start to her residency after venue staff failed to recognise her and refused to let her in the building.

She writes, "Tried getting into rehearsal at the Apollo... My face everywhere outside but no one would let me in. Knocked for a while. Humbling. Very humbling."
