The Sunday Mirror says Rooney is to snub Ferdinand's summer wedding... because he is still furious his Man Utd team-mate missed his.
Rio, 30, plans to wed fiancée Rebecca Ellison, 28, in June.
The pair have been together for seven years and have two sons, Lorenz, two, and Tate, one.
Three locations - St Lucia, Las Vegas or Richard Branson's Caribbean Necker Island - are being considered for the venue.
Relations between England footballers Wayne and Rio have been icy since Ferdinand and Rebecca failed to turn up at Rooney's £5million wedding in Portofino, Italy, last June.
A pal said: "Invitations to the wedding are expected to go out soon. Rio suspects Wayne is likely to decline but he's still going to send him one. It looks like he'll be wasting a stamp." Another friend added: "Wherever it is held, it will be no expense spared. Rebecca doesn't like the limelight so there'll be no exclusive magazine deal. But she and Rio have very good taste and guests can be sure of it being a spectacular event."
