Iggy Azalea's got a new riding partner who's also trying to buck a slew of personal drama -- Kesha's now saddling up with the rapper.

The duo look like they're trying to present a united front in the pic, which Iggy posted. More proof these chicks ain't playing -- their horses are named Biz and Defender.
