The Dutch designers celebrated their famous fragrance's 10th anniversary in Paris.

With rose-filled cannons in the entry hall, designers Viktor & Rolf were out to, well, Flowerbomb the guests that came out to fete the 10th anniversary of their fragrance.

Michelle Rodriguez, Tori Amos, Charli XCX and photographer Ellen von Unwerth were among those that celebrated at Paris’ popular concert hall Le Trianon, which was bathed in pink light.

Dutch duo Viktor Horsting and Rolf Snoeren debuted the L’Oreal-backed scent a decade ago with a now-famous grenade-shaped bottle.

Amos took to the white grand piano on stage, flanked by even more flowers. "My dear friends Viktor and Rolf, this is a special, mostly requested, set just for you," she said, before launching into hits songs such as "Northern Lad," "Hey Jupiter," and, of course, "Happy Birthday."

Guests were served miniature pink cakes designed to resemble the fragrance's packaging before Charli XCX took the stage to sing her hits "Boom Clap" and "Break the Rules."

Rodriguez has been making the rounds at Couture Week while taking a break from Hollywood. "I am actually holding off because I want to do something completely different than anything I’ve ever done before, so I’m just snooping around town with new directors and some interesting writers," she said.

After a week of gowns and a bevy of beauty parties, couture week closed, and not a moment too soon. After Versace's orchid-filled lucite runwayGiambattista Valli and MAC’s collaboration celebration, Lancome’s big birthday and Viktor & Rolf’s Flowerbomb bash, we’re wondering if there are any flowers left in France.
