Find out what went into crafting RiRi's standout moment from the sci-fi flick in this bonus feature from the Blu-ray and DVD, out Nov. 21.)

Reaction to Valerian and the City of a Thousand Planets may have been mixed, but one thing was unanimous: Rihanna playing a shape-shifting alien named Bubbles was a highlight. In this behind-the-scenes featurette, debuting on ET, RiRi reveals which of her many looks -- disco queen, French maid, Cleopatra and more -- was the hottest. Not like sexy, but actually hot.

"I loved the nurse outfit. That one was a tricky little number, because it was all latex," Rihanna says. "Literally, I had to take breaks to, like, towel down the sweat out of my costume. It was crazy. But I did lose some weight for the next scene, which was tribal and my stomach was all out!"

Valerian was a passion project for visionary director Luc Besson, one he spent many, many years attempting to bring to the screen, and he told ET that he cast Rihanna once she proved to him that she is "serious about acting."
