We explore the CP violation in B -> rho gamma decay processes in the presence of the anomalous right-handed t ($) over bar dW and t ($) over bar bW couplings. The complex anomalous top coupling can be a source of the new CP violation and lead to a sizable time-dependent CP asymmetry in B-0 -> rho(0)gamma decay. (c) 2005 Elsevier B.V. All rights reserved.
