Resumen
We gathered a multiwavelength dataset of two well-known LBVs. We found a com plex mass-loss, with evidence of variability, such as has been seen previously. In addition, our
data reveal signatures of collimated stellar winds. We propose a new scenario for these two stars
where the nebula shaping is influenced by the presence of a companion star and/or fast rotation.
