There will two very special guests at today's racing.
Laxey teenager Samantha Barks (pictured) will sing the Manx National Anthem before the start of the Ducati Parade Lap.
She finished third in the BBC television programme 'I'd Do Anything' at the weekend.
Also in the Grandstand will be Manx cyclist Mark Cavendish, just back from competing in the Giro d'Italia where he won two stages.
He is the first British rider to ever do so in a Grand Tour event.
The Ducati Parade Lap will feature some big names from TT's past, including Carl Fogarty, and Tony Rutter.
The son of TT legend Mike Hailwood will also be doing a lap on his father's winning 1978 Formula One Ducati.
The parade will start at 10.45 this morning.
