The couple parted ways in October (11) after four years together, but they sparked speculation of a reunion last month (Feb12) after they were spotted together in Los Angeles and in Ireland, where Hamilton supported her at a solo show.

They later enjoyed a romantic two-day trip to Monaco, and now Scherzinger has flown Down Under to support Formula One driver Hamilton at his upcoming race.

The stars were spotted chatting with Lenny Kravitz in the paddock aheadof Sunday's race, which Hamilton will start in pole position.
