Bryan Ferry's son is reportedly the jealous guy now that love's the drug for his Roxy Music frontman father - who's now dating his ex.
Ferry, 63, has been spotted out and about in London with Amanda Sheppard, 27, who dated his son Isaac, 23, five years ago.
But Isaac is reported to have been unaware of the relationship while her pals are said to have dubbed Ferry senior 'The Pensioner'.
Ferry divorced his ex-wife Lucy in 2002 after 20 years of marriage. They have three other children - Otis, 26, Tara, 18 and Merlin, 17.
Otis, a fox hunting enthusiast, is currently in Gloucester Prison awaiting trial for perverting the course of justice over allegations that he stole camera equipment from two women who were monitoring a hunt near Stow-on-the-Wold in November last year.
His girlfriend, Francesca Nimmo, was arrested on November 15 on the same charge
