Besides, a setlist contained full of new songs, Lady Gaga’s live performance at the iTunes Festival featured a guest appearance in the audience.

Away from the spotlight since her participation in this year’s Oscars, Adele decided to honor the live performance of the pop star's VIP area of the Camden Roundhouse, alongside other celebrities like the singer Niall Horan of One Direction and star of the series Sherlock, Benedict Cumberbatch.

Back home, the British star congratulated Lady Gaga via Twitter. "Lady Gaga brilliant as always, thank you for a wonderful evening! "wrote the singer with the hashtag # MANiCUREisthebest in reference to Gaga's new song.

The presence of Adele was seen only when she left the show and in her vehicle, which was photographed by a paparazzi, without makeup.
