'The Big Bang Theory' actor Jim Parsons is currently promoting his new animated film 'Home', which also stars Rihanna, and he revealed that he keeps singing the Bajan beauty's songs to her when they pop into his head. 

The pair provide voices for two of the main characters in the new DreamWorks movie and Parsons explained to Jimmy Fallon that he will be sitting with Rihanna and suddenly one of her hit singles will pop into his head so he sings it aloud to her, which she doesn't like:

"I've been doing France with Steve Martin and Rihanna and I, being around her, I... her songs keep coming on in my head. And I'll keep, like, singing, 'Yellow diamonds' - just out of nowhere, I'll be doing it. And first off, her reaction is always, she'll look at me and go, 'That gives me chills. And not in a good way. Please stop.' But the second thing I thought was, what if she was doing 'Bazinga' [his catchphrase from The Big Bang Theory] the whole time we were doing press? I might go, 'Would you shut up?' I thought it was a compliment, you know?"
