Bono has recorded a duet of Lady Gaga's 'Telephone' with his wife Ali Hewson.
The U2 frontman unveiled the version of the song at his daughter Eve's 21st birthday party in Las Vegas on Saturday (07.07.12), where it was played to assembled guests including music mogul Jimmy lovine and Wilmer Valderrama.
Bono himself introduced the track - originally performed by Lady Gaga and Beyonce Knowles in a 'Bonnie and Clyde'-themed video - before sending two bottles of Dom Perignon champagne to his daughter's table at the party at 1Oak nightclub at the Mirage hotel.
According to the New York Post newspaper, other guests at the event included 'Transformers' director Michael Bay and basketball star Kobe Bryant, while rapper Fabolous gave a shout out to Eve and dedicated a song to her.
It was the second-leg of celebrations for Eve, who earlier in the day had enjoyed a dinner with family and friends at Tao Las Vegas.
However, Bono did not celebrate too hard on Saturday, as the day after he attended Cirque du Soleil's 'Love' show at The Mirage - which is based on the music of The Beatles - where he met performers and posed for pictures alongside his wife Ali.
