Whether Jennifer Lawrence knew she would win at the Oscars on Sunday night or not she did know, that as a hotly tipped nominee, all eyes would be on her.

For any big occasion a girl likes her hair to be just so, which is why Lawrence waited until after the Oscars, actually the very next day, to get her honey blonde hair darkened to her character Katniss Everdeen's jet black hue.

Lawrence may have been partying into the early hours of Monday morning but we spied her emerging from the Rossano Ferretti salon in Beverly Hills yesterday with all-new hair. So why the rush? Well, Lawrence is reshooting scenes for the second film in the trilogy, The Hunger Games: Catching Fire.

According to TooFab.com the star was in high spirits (wonder why that could be?), telling staff at the salon she was heading to Hawaii for the reshoot.
