Ashlee Simpson plans for an `eclectic` wedding?

London: Singer Ashlee Simpson and actor-fiance Evan Ross are reportedly planning to organise an `eclectic Bohemian` wedding.

The couple will tie the knot at the actor`s mother Diana Ross` estate in Greenwich, Connecticut on August 31, reportedly.

Simpson, 29, is picking up mismatched dresses for her bridesmaids, a source said. The `Catch Me When I Fall` singer proposed Ross, 25, after six months of dating in January.
