Lewis Hamilton showed his gratitude for girlfriend Nicole Scherzinger's support during his F1 championship battle by giving her a present that meant more than any expensive jewels – an incognito tour of his home town Stevenage.

He took the stunning brunette, a singer with American group the Pussycat Dolls, to see the local church and his old school before dropping in at home for a roast dinner cooked by his stepmum Linda.

The 23-year-old - who became the youngest world champion in the sport's history at a thrilling race in Brazil on Sunday - said Nicole had been "incredible". "I'm crazy about her. She brings out the good in me," was how the racing ace summed up his feelings for his Hawaii-born love.

"I wanted to show her where I grew up. We drove past where I was baptised, my old school… and old house. I have happy memories of the town – and I still go to the dentist in Stevenage," he added.

After seeing the sights the duo, who've been dating for a year, slipped unnoticed into a screening of Bond movie Quantum Of Solace at the local cinema.

Nicole also accompanied her guy as he received a hero's welcome from 1,000 workers at the McLaren team's headquarters in Surrey. Delighted Lewis was given a tickertape reception – and a toy model of a McLaren supercar bosses have promised him if he wins two more world titles.
