A source close to Usher said the couple was favorable for a long time and shared some "passionate kisses".
"They had a great time last weekend and wanted to see, a private place immediately afterwards. Are well known to each other. But there has always been a bad time. There were some long, passionate kisses. There's definitely a spark between them" , the source told The Sun.
According to femalefirst.co.uk, the two singers enjoy spending time with another in the Coachella music festival in Los Angeles last weekend and decided to meet in New York a few days later.
The source added: "It would have been too obvious to go somewhere in Los Angeles and they were both back to New York to work commitments."
