When The Sun isn't busy hacking your phone or printing pictures of tits, it's trying to publish celebrity scandals regardless of what percentage of the story they can prove is real. Detective Ronaldo is on the case
I don't really understand the story but I think this is supposed to show that The Sun is going to print a story about him talking to a mysterious girl called Andressa in a sexy way. Distracting side stories to this are that Ronaldo doesn't know who she is, whether she exists at all and also that he was giving an interview to another reporter at the time the phone calls were supposed to have happened.
I think somehow Twitter is related too which just goes to show that you should never listen to anything that a girl on the internet tells you because it's a scam designed to make you constantly spend all of your money to make a girl have sex with you, or a fake ad that takes you to some cinema site where you have to watch terrible movies and make you not have any fun. And in that way it's actually a lot like girls in real life really.
