Nicole Scherzinger has congratulated Lewis Hamilton on winning his race.

The former Pussycat Doll said she she was "proud" of the Formula One race car driver when he took the pole position during a qualifying race in Melbourne on Saturday (15.03.14) ahead of Australia's Grand Prix on Sunday (16.03.14).

Nicole couldn't hold back her excitement as she tweeted: "Congratulations @LewisHamilton So proud of u 4 taking pole position! First race of the season! @f1 #AustralianGP Race ur heart out babe! xo (sic)."

Nicole's public display of affection is the latest confirmation that pair have sorted out their differences following an emotional break-up in September, as the two were spotted enjoying a romantic holiday together in Rome, Italy last week.

Lewis - who was raised as a Roman catholic - said he was "humbled" when he took to Instagram to post a picture of himself posing alongside his on-off girlfriend, Nicole at the The Sistine Chapel.

He wrote: "This was a great day....truly humbled by the Sistine Chapel plus there with my wifey. #godisthegreatest #sistinechapel #blessed (sic)."

The pair also took in several other sights during their romantic weekend including the Colosseum, Piazza Navona and the Gianicolo Hill.

While the couple have endured numerous break-ups throughout their five year relationship, a source told the Daily Mirror newspaper their reunion is for good.

The source revealed: "[Lewis] adores Nicole. They are so in love. Their circle of friends think that now they're back together they will be ­married within months."
