John Lennon's musician son Julian is to feature on Aerosmith's next album.
The British rocker was recruited by Aerosmith frontman Steven Tyler to contribute back-up vocals for the Walk This Way hitmakers' forthcoming release.
Lennon has posted a photo of himself in the recording studio with Tyler on his page with a caption promising "more to come".
A source tells Britain's Daily Express, "Julian is a big Aerosmith fan and has been asked to sing backing vocals on the new album by Steven, who loves Julian's voice as it's reminiscent of John's. Julian's been in his element. It's hoped he'll be joining them on tour too."
