Last year, she scored the best supporting actress Oscar for her role in Les Misérables.
And Anne Hathaway made her triumphant return to Hollywood's Dolby Theater Sunday in a black Gucci halter gown featuring a dazzling disco bodice.
The 31-year-old actress displayed her toned arms and back in the vampy dress, which she paired with a patent leather clutch and pumps.
The Don Jon star dutifully presented the statuette to Jared Leto for his heartbreaking role as the vulnerable yet flamboyant transgender character Rayon in Dallas Buyer's Club.
Anne recently ditched her stylist of a decade - Rachel Zoe - in favour of Penny Lovell - according to The Hollywood Reporter.
Lovell also provides red carpet looks for Rose Byrne, Taylor Schilling, Bella Heathcote, and Mary Elizabeth Winstead.
Not seen Sunday was Hathaway's husband, producer Adam Shulman, whom she tied the knot with in 2012.
The Rachel Getting Married star will soon begin shooting Nancy Meyers' The Intern alongside Robert De Niro, after replacing Reese Witherspoon. The brunette beauty will reprise her voiceover role as Jewel the parrot in the animated sequel Rio 2 coming out April 11.
Anne head butts director and star Dan Fogler in the comedy Don Peyote - due out May - alongside Josh Duhamel and Topher Grace. And the Princess Diaries actress reunited with her Dark Knight Rises director Christopher Nolan for the sci-fi epic Interstellar - due out November 7.
The IMAX flick - shot in Iceland, Canada, and LA - also stars Matthew McConaughey, Jessica Chastain, Matt Damon, John Lithgow, and Ellen Burstyn
