Who does Rouge the Bat love besides Shadow and Knuckles

A Sonic the Hedgehog 2006 game guide says Rouge has feelings for both Shadow and Knuckles, and nobody else was mentioned. She does not love Tails as she only kissed him on the cheek in Sonic X to lure him into doing something for her. Rouge is also known to flirt with many males in the Sonic series as of her flirtatious nature.
