ABU DHABI, United Arab Emirates - Lewis and former arch-rival/enemy Fernando are not hiding away their new-found affection. Lewis might be missing his Pussycat Girl, but isn't this going to extremes? There's a theory...Mutual self-interest may have motivated the new friendship between Alonso and Hamilton, reckons at least one source. In 2007, the pair clashed spectacularly as McLaren team mates and since then they've maintained a healthy distance but at the 2011 Abu Dhabi GP they were praising each other's talents.'LOVED THE FIGHT'Then, when they finished first and second in the race, they shared an unusually warm hug.Hamilton explained to Italian broadcaster Rai: "I loved the fight with Fernando, I think he's the strongest driver."With Sebastian Vettel out of the race with a rare retirement but having started from pole as per usual in his meteoric back-to-back championship season, the correspondent for La Stampa newspaper smells a rat.With the 2012 season now looming and Red Bull's dominance to possibly continue, journalist Stefano Mancini calls the new friendship between Hamilton and Alonso "an unholy alliance against Vettel".Shame on him!
