Lupita Nyong'o

Lupita Nyong'o spent her birthday with Angelina Jolie and Brad Pitt yesterday (01.03.14).

The '12 Years A Slave' star celebrated turning 31 by gorging on a glamorous dinner, hosted by Grey Goose, at the Sunset Tower Hotel in Los Angeles along with her co-star and his long-time love.

A source told E! news: "Angie looked gorgeous per usual. She and Brad were adorable and talked to everyone!"

The couple - who got married in 2005 - were reportedly the first of the guests to leave, but they "stayed for a nice amount of time".

Also in attendance was Chiwetel Ejiofor, Michael Fassbender, Steve McQueen and Lupita's close friends and family.

The stunning actress took to her Instagram account after the festivities to share a picture of her friends and the yummy gluten-free cake they had arranged for her.

Lupita accompanied the photograph with the caption: "Birthday surprise from the #12YearsASlave family. Feeling the love. (sic)".

It was a double celebration for the stars last night as their slavery movie received five prizes - including Best Feature, Best Screenplay, Best Director for Steve, Best Supporting Actress for Lupita and Best Cinematography - at the Independent Spirit Awards.

Meanwhile, the '12 Years A Slave' cast look set for another busy night tonight (02.03.14) as the film has been nominated for nine accolades at the Oscar Awards, held in Los Angeles.
