Celebs raced over to Singapore last weekend for the 2009 Formula 1 F1 Rocks.  The 3-day long music festival in Fort Canning Park, which kicked off the Singapore Grand Prix, was hosted by fashionista Lindsay Lohan.  Pussycat Dolls Nicole Scherzinger, who dates Formula 1 champion Lewis Hamilton, pulled out of her hosting duties earlier this month, but still managed to make an appearance at the ultra glam event.  Nichole must have coordinated with her beau before choosing this stunning orange Alexander Wang number, which was a perfect match with his racing team polo!

Lohan was joined by girlfriend, Sam Ronson, who happened to be DJing at the event.
