The audience thought that the singer behaved inappropriately when he “locked lips” with trumpeter Brian Newman at a show in Las Vegas (USA).

According to US Weekly, the video recording the image of Lady Gaga kissing Brian Newman on stage received many mixed opinions from fans on Twitter. The female singer lovingly looked at her co-star and kissed him after singing the line “Darling, kiss me!”.

One user commented: “Oh my God! Brian is a married man. Gaga should behave more properly.” Another person said Brian’s wife was also at the show. Many fans defended the female singer . They believe that Lady Gaga’s actions only add more appeal to the performance, similar to her romantic moment with actor Bradley Cooper at the Oscars in February.

The incident took place on the evening of June 15 (US time) during the female singer’s Las Vegas Enigma show series. According to People, Lady Gaga and Brian Newman were close friends before she was famous. She is also the godmother of Brian’s daughter. A source from the female singer said that the moment the two kissed was simply for show.

In February, Lady Gaga broke up with her manager Christian Carino after several months of engagement. In 2016, she also broke up with Taylor Kinney after getting engaged. In the documentary  Gaga: Five Foot Two , Lady Gaga said that the more successful she became in her career, the more difficult she became in love.
