Couple reported to have had pre-ceremony blood tests
The couple, who got engaged in April 2007, are said to have had blood tests, which are required to obtain a wedding licence in the US, in the town of Jackson Hole, Wyoming.
Local residents have tipped off reporters.
‘Jackson Hole bigmouths swear they took blood tests and got licences so could be they already are, or soon will be, filing joint returns,’ a source tells the New York Post.
Harrison, 66, and Calista, 44, who is mum to adopted son Liam, 8, have been together since 2002.
The Indiana Jones star has four children from his previous 2 marriages.
