A source close to Usher said the pair have been friendly for a long time and have shared some "passionate kisses".
"They had a really good time together last weekend and wanted to see each other again, somewhere private straight after. They’ve known each other for a long time. But it’s always been bad timing. They’ve had a few long, passionate kisses. There’s definitely a spark between them," The source told The Sun.
According to female first.co.uk, the two singers enjoyed spending time with one another at the Coachella music festival in Los Angeles last weekend and decided to see each other again in New York a few days later.
The source added: "It would have been too obvious to go somewhere in LA and they were both going back to New York for work commitments." (IANS)
