Lady Gaga (33) and R&B singer Ashanti (39) were both present and came on stage to sing a song together. The two performed a jazzy version of Ashanti’s hit Foolish together. Later Lady Gaga also sang the song Just a Gigolo, I Ain’t Got Nobody with Newman. Gaga can be found a lot in Las Vegas at the moment, because she gives two series of concerts in the Park Theater. The one show, Enigma, consists of its biggest hits. The other, Jazz and Piano, consists of major American hits and stripped down versions of her own work.
