Her already amazing year just keeps getting bigger and better.

At the very least, more lucrative.

Best supporting actress winner Lupita Nyong'o, who gave a heartfelt speech after winning the Oscar for 12 Years a Slave, joins the ranks of Kate Winslet and Julia Roberts as one of Lancôme's ambassadors. Ads will first appear in September.

"I am truly honored to join the Maison Lancôme, a brand with such a prestigious history that I have always loved. I am particularly proud to represent its unique vision for women and the idea that beauty should not be dictated, but should instead be an expression of a woman's freedom to be herself," Nyong'o said in a statement released by the French beauty house.

Nyong'o also popped up in Miu Miu's spring 2014 campaign, and sat front row at the brand's recent show.

Throughout awards' season, Nyong'o dazzledstyle watchers with her impeccable and often daring fashion sense, which ranged from Chanel to Gucci to that red Ralph Lauren cape dress. She was both deeply elegant and elegantly fierce.

"I had to give a speech about beauty right before the Oscars," she told WWD, "and for me, beauty is a compassion for yourself and those around you. And I think that in focusing on that, the light inside illuminates the beauty outside. The idea that Lancôme now has a few actor ambassadors is significant because actors are not just faces, they are spirits that people enjoy and relate to more than in an aesthetic way. We have the privilege of standing for something other than just looks."

She'll make her first post-Oscars appearance back in Hollywood at the April 12 GLAAD Media Awards, reports E!.
