Nelson Piquet will be racing this weekend after Felipe Massa invited him to compete in his International Challenge of the Stars charity kart race, which will be held at a brand new circuit in Florianopolis, Brazil.

Last weekend, Piquet finished eighth overall from 43 entrants in the SuperPro category of the SKUSA SuperNats kart event in Las Vegas, one position behind Michael Schumacher.

This year marks the fifth International Challenge of the Stars, the event having been launched in 2005 by Massa, who won the event himself in 2006, with Piquet finishing in the runner-up spot. Michael Schumacher won in 2007, with Piquet retiring from mechanical problems after starting on pole. Rubens Barrichello won in 2008.

The race will see Felipe Massa returning to competitive action for the first time since his accident in July in qualifying for the Hungarian Grand Prix. Other drivers confirmed for the event include Schumacher, Barrichello, Vitantonio Liuzzi, Antonio Pizzonia, Tony Kanaan and Christian Fittipaldi.

British Eurosport 2 will be showing the event live at 18:00 on Saturday 28 and 13:00 on Sunday 29.

"I have never had so much fun as racing in Las Vegas," said Piquet, "and I was really pleased finishing eighth against the best karters in the world. Now I'm happy that I can be back in Brazil to do Felipe's race this weekend. It's going to be very competitive as usual, there are some great drivers confirmed and I want to try to win it this year!"
