 "We sang the classic song 'Bésame mucho' with Michael Bublé, but we created a different version with tango elements, that make it really sexy.As for Robbie Williams, it was a dream that came through to collaborate with him since I really admire his work.I invited him to sing with me a 'mambo' song, "Muñequita linda" that was made popular by the voice of Nat King Cole.
