Bipasha Basu: A sucker for two hero projects?

what's with bipasha basu? the model-turned-actress seems to have cottoned on to two-hero-two-heroine projects with a vengeance. after her debut ajnabee which also co-starred bobby deol, akshay kumar, kareena, she's now gone ahead and signed aslam siddiqui's nehle pe dehla which again has two lead pairs. this time bipasha shares the limelight with sunjay dutt, saif ali khan and kim sharma.also she's doing the david dhawan directed chor machaaye shor which has two lead pairs too - bobby deol, shilpa shetty, shekhar suman and herself! may be it's just that she believes that 'four heads are better than two!'
