Bellamy, on loan at Cardiff from Manchester City, reportedly told Dutch fans in a pub that he would join Feyenoord if Cardiff are promoted, but Beenhakker is not ready to consider a deal for the 31-year-old.
'I got him on the phone, I sent him a detailed text message, to ask him if he will stop the nonsense,' Beenhakker told AD Sportwereld.

'I said to him, "Friend, you can say anything you want, but while you are still owned by Manchester City, I cannot".
'It is as simple as that. As soon as he is free from his club, he knows where he can find me. Until then, these are cowboy stories.
'I saw he said in the media, "Beenhakker takes me seriously". That bothers me. There's just a huge price tag on him. If it comes off, then we can talk.'
Meanwhile, Beenhakker revealed Feyenoord may seek compensation from the Danish Football Association as Jon Dahl Tomasson remains sidelined with a tendon injury suffered at the World Cup this summer.
Beenhakker dismissed suggestions the 34-year-old's contract may be cancelled, but compared the situation to the injury suffered by Holland's Arjen Robben, for which Bayern Munich have sought compensation, with UEFA set to rule on the dispute with the KNVB.
'I have had brief contact with the Danish Football Association,' Beenhakker said. 'We have decided to wait and see how UEFA handles the case of Arjen Robben.
'We are in exactly the same situation with Tomasson. I recognise he is not as big a name, and we are a smaller club than Bayern, and we do not make so much noise.
'But if compensation is paid to Bayern, then we will go to the Danish FA. The case of Robben will set the precedent in Europe.'
