Robbie Williams is/was (I don't know) a teenage heartthrob. He sings love songs etc. Interviews with him are fluff pieces consumed by teenage girls. A bit of flirting might be more in context even if it is still lame.
A sportsman just off the cricket field being interviewed specifically about his performance on the field for a primarily male audience is quite a different thing. The context is completely wrong for some ad-lib flirting. The female interviewer knows the audience is primary male and it is just thoroughly embarrassing for everyone concerned.
