The couple, who reconciled last year, were spotted partying at different places here over the weekend. But their friends insist they are still together and just have a lot going on.
"Chris ain't trying to hear no nonsense today. It is simple, he with Ri. They are cool and if and when something changes between them, that's between them. They both have a lot going in their careers right now and just doing them and focused on they work," femalefirst.co.uk quoted a source as saying.
"They have been trying to connect, but it hasn't been clicking for them. It ain't like Rihanna got time to just chill and run through, she's on tour and her schedule is way too tight," added the source.
Brown recently revealed he loves collaborating with Rihanna and they have a great working relationship because they are so similar.
