We present thick de Sitter brane solutions which are supported by two
interacting {\it phantom} scalar fields in five-, six- and seven-dimensional
spacetime. It is shown that for all cases regular solutions with anti-de Sitter
asymptotic (5D problem) and a flat asymptotic far from the brane (6D and 7D
cases) exist. We also discuss the stability of our solutions.
