We present multi-instrument and multi-wavelength observations of the famous LBV star Pistol Star. These observations are part of a larger program on early O stars at different metallicities. The Pistol Star has been claimed to be one of the most massive star known, with 250 solar masses. We present preliminary results based on X-shooter spectra, as well as observations performed with the VLTI-AMBER and the VLT-NACO adaptive optics. The X-shooter spectrograph provides simultaneously a spectrum from the UV to the K-band with a resolving power of ˜15000. The preliminary results obtained indicate that Pistol Star has similar properties to η Car, including shells of matter, but is also a binary.
