Nicole's pit stop Down Under

Scherzinger was seen cheering for her beau in the qualifying session, the first race of the season.

Hamilton took pole in Saturday's qualifying session ahead of teammate Jenson Button while Romain Grosjean of team Lotus was the surprise package as he took third place.

Hamilton and Scherzinger broke up at the end of 2011 after a three-year on-off relationship because conflicting work commitments were reportedly keeping them apart.
