Open champion Phil Mickelson reportedly hosted a party on his private jet following his victory at Muirfield.
The American pro secured the Claret Jug by three shots just a week after winning the Scottish Open.
Mickelson's caddie Jim 'Bones' Mackay was invited to attend the celebrations on the 43-year-old's private jet to the United States, according to The Sun.
Mickelson has won every Major tournament apart from the US Open.
