  We present evidence for a Spitzer-selected luminous infrared galaxy (LIRG)
behind the Bullet Cluster. The galaxy, originally identified in IRAC photometry
as a multiply imaged source, has a spectral energy distribution consistent with
a highly extincted (A_V~3.3), strongly star-forming galaxy at z=2.7. Using our
strong gravitational lensing model presented in Bradac et al. (2006), we find
that the magnifications are 10 to 50 for the three images of the galaxy. The
implied infrared luminosity is consistent with the galaxy being a LIRG, with a
stellar mass of M_*~2e11 M_Sun and a star formation rate of ~90 M_Sun/yr. With
lensed fluxes at 24 microns of 0.58 mJy and 0.39 mJy in the two brightest
images, this galaxy presents a unique opportunity for detailed study of an
obscured starburst with star fomation rate comparable to that of L* galaxies at
z>2.
