Berlusconi Sleeping (With Hookers) In Putin's Bed

Yes, there are audio recordings of Italian PM Silvio Berlusconi with prostitutes, and yes he asks one to participate in a three-way, but the most amusing fact here is that Berlusconi named one of his beds after Vladimir Putin:

One of the conversations appears to back claims that Italy's leader has a giant bed with a connection, as yet unclear, to his Russian counterpart, Vladimir Putin.

After an exchange in which the prime minister seems to be offering a present to D'Addario, he says to her: "I'm taking a shower." He then asks her to wait on the big bed. She asks which one. He replies: "Putin's".

Right. Is that some sort of little joke or does Putin have a bed at Silvio's vacation home? And if he does, does he know what Silvio's doing in it?
