Romain Zago dropped the sweet, sweet compliment earlier this month during a deposition in the now-infamous smelly vagina legal battle between Joanna and Brandi.
According to docs, obtained by TMZ, Romain told Brandi's attorney -- "If you want to know the answer to this stupid comments from your client, (Joanna's) vagina smells amazing. And I swear on God, Jesus, my father, my brothers."
Brandi's lawyer asked Romain if Joanna smells better or the same as the other women -- and he said, "Better than any other woman in the world." Ringing endorsement, for sure.
Romain also accused Brandi of being a horrendous bully who damaged his marriage.
Joanna filed to divorce him just 4 days before the deposition, and he STILL testified pro vajayjay!
