*Race car driver Lewis Hamilton and Pussycat Dolls singer Nicole Scherzinger have hit the proverbial wall in their relationship.

After dating for more than two years, the two have called it quits, according to the Associated Press.

The 25-year-old Formula One driver and 31-year-old pop star said in a joint statement released Monday that they wanted to concentrate on their careers.

The two met in Nov. 2007 at the MTV Europe Awards in Munich. Scherzinger, a constant presence in F1’s paddock since, was track side a year later when Hamilton won his first F1 title at the Brazilian Grand Prix.
