We present a comparison of the Large Magellanic Cloud (LMC) at 1.4 GHz emission with Spitzer Legacy survey data at 3.6 - 24 micron m in the LMC. Source extraction and aperture photometry were performed using the Spitzer Astronomical Point Source Extractor for the deep Spitzer Legacy images. Using mid-IR-to-radio spectral energy distributions (SEDs), Spitzer colors, and infrared luminosities, we identify tentative candidates for submillimeter galaxies (SMGs) behind the LMC. These galaxies are very massive and young in nature and seen during their formation epoch with an inferred star formation rate (SFR), likely to be exceeding 100-1000 solar mass per year. The Herschel observations of the Magellanic Clouds will give us clues about the nature of background galaxies behind the Magellanic Clouds and their redshift distribution in the universe.
