"Chris ain't trying to hear no nonsense today. It's simple, he with [Rihanna]. They're 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," the source said.

"They've 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," the insider continued.
