We use a combination of VJHK and Spitzer [3.6], [5.8] and [8.0] photometry, to determine IR excesses in a sample of LMC and SMC O stars. This sample is ideal for determining excesses for two reasons: 1) the distances to the stars, and hence their luminosities, are well-determined, and 2) the very small line of sight reddening to the stars minimizes the uncertainties introduced by extinction corrections. Preliminary results give IR excesses much larger than expected from their mass loss rates derived from the Vink et al. (2001) formulae. This is in contrast to previous wind line analyses for many of the LMC stars which suggest mass loss rates much less than the Vink et al. predictions. Together, these results indicate that the winds of the LMC and SMC O stars are strongly structured (clumped). This work is supported by NASA's ADAP.
