Adele and her fiance Simon Konecki enjoyed a rare date night at a secret Lady GaGa concert.

The couple, who welcomed their son, Angelo, into the world in October 2012 and have kept a low profile since then, were among the star-studded audience at the 'Applause' hitmaker's intimate gig at member's club Annabel's in London last night (06.12.13), during which she performed tracks from her new album 'ARTPOP'.

The event, sponsored by Belvedere Vodka, supported the Belvedere red Special Edition bottle, which raises proceeds for the Global Fund, the world's leading financier of programs to fight HIV/AIDS in Africa.

Speaking at the show, Lady Gaga, 27, said: ''I think it is very important to join the fight against Aids and HIV and think it is wonderful that Belvedere and Annabel's are supporting and had this event this evening. The more we can educate people the more we control the problem. I think it is really wonderful they are involved and think all major corporations should join the fight.''

Sting and Trudie Styler, Jonathan Rhys Meyers, Emma Watson, Bar Refaeli, Douglas Booth, Eddie Redmayne, Jessie J, Boris Becker, Bryan Ferry, Hayley Atwell, Michael McIntyre, Emeli Sande, Tinie Tempah, Christopher Kane, Richard E Grant, Philip Treacy, Suki Waterhouse and James Blunt were also spotted at the event.
