Nicole Scherzinger, who has rekindled her love affair with Lewis Hamilton earlier this year, took her place of pride in the race paddock in Melbourne, Australia.
The former Pussycat Doll kept covered up in a large grey fedora and shades, which she teamed with a white top and looked effortlessly cool in, the Daily Mail reported.
The couple broke up at the end of 2011 after a three-year on-off relationship because conflicting work commitments were reportedly keeping them apart.
However, the pair reunited and have been spending a lot of time with each other since their reconciliation.
Scherzinger, 33, who was recently booted off the X Factor USA, was in good spirits and chatted with her boyfriend.
The 27-year-old driver, who has a 10 million pounds-per-season deal with McLaren, took the time to hang out with A-List stars ahead of his second practice session of the Australian Formula One Grand Prix at Albert Park.
Rock star Lenny Kravitz dropped in to see Hamilton and was given a personal tour of his Formula 1 vehicle.
The 47-year-old appeared to be in awe of the young race driver and his impressive piece of machinery as the pair walked round the paddock.
A stubble faced Kravitz looked every inch the cool musician in a pair of black sunglasses, beanie, and black leather jacket.
The American Woman hitmaker was given the VIP treatment as Hamilton explained in detail exactly what each part of the multi-million pound car did.
He even gave the singer a hands-on close up of the steering wheel as the two men bonded over big boys toys, but stopped short of letting him take the car for a spin.
