Jared, who scooped the prize for best supporting actor for his performance in Dallas Buyers Club, was in high spirits as he headed to the Vanity Fair Oscar party, as he photo bombed Anne Hathaway on the white carpet.
Lupita, who received the best supporting actress trophy, clutched her golden statuette at the glitzy bash, after changing from her blue Prada gown to a white dress with a beaded green neckline .
The pair were joined by a host of star-studded names such as Oscars host Ellen DeGeneres, Leonardo DiCaprio, Will Smith and his wife Jada Pinkett Smith, and the Hemsworth brothers - Liam, Chris and Luke - as they celebrated through the early hours.
Meanwhile, Britney Spears, sisters Kim, Khloe and Kourtney Kardashian and Sharon and Kelly Osbourne were amongst those who joined Sir Elton John and David Furnish at their annual Academy Awards viewing party at West Hollywood Park in Los Angeles, in aid of the Elton John Aids Foundation.
Ed Sheeran, who provided the music, joked about the big names in the crowd. The Lego House singer said: "I felt excited to play tonight. It's not my usual clientele."
Host Elton said: "This is our 22nd event and each year, it seems to get bigger and we raise a lot of money."
Sharon, who wore an Alexander McQueen gown, was glad that Steve McQueen's harrowing drama 12 Years A Slave won. She said: "I've seen it three times. It moved me so much that I had to see it again, because a lot of the time, I couldn't watch so I made myself watch it again. It's a fabulous piece of work."
