Blazars are characterized by extremely high optical variability, strong and variable polarization and very rapid flux variability over the entire electromagnetic spectrum, from radio to very high energetic gamma-rays. These extragalactic objects are sub-divided into BL Lacs and FSRQs depending on optical emission line properties. We have undertaken the study of well known FSRQ 3C 273 with data available from XMM-Newton telescope. XMM-Newton observed the blazar for a time period more than one decade, from June of 2000 to July, 2013 by XMM-Newton in both optical/UV and X-ray bands. X-ray spectra of this source shows excess emission in lower energy band. Fitting of the X-ray spectra of this source is difficult with conventional simple power law used for typical FSRQs. So we use a different approach for spectral fitting in the energy range 0.3-10 keV and try to explain the hidden physical conditions.
