Pernilla Wahlgren and Per Andersson have been seen together in SVT's Christmas calendar "Panik i tomteverkstan".

And on Saturday we get to see them together again as hosts of the Melodifestivalen.

But we could have seen them on the Mello stage together before - if Pernilla Wahlgren had not said no.

- I think I got a song sent to me where the suggestion was that we would do a song together.

It was called Friday Cozy, she says.

It must have happened a few years ago, according to Wahlgren.

And the otherwise so playful Per Andersson is sincerely surprised when he suddenly hears this for the first time during the interview with SVT Nyheter.

- I can play it for you, says Pernilla Wahlgren.
