Alessandra Ambrosio Parties In Her Panties At Warner Music Group's Grammy Celebration!

Jennifer Lopez has some competition!
Alessandra Ambrosio had jaws on the floor Sunday night at Warner Music Group‘s Grammys after party in West Hollywood.
The Victoria’s Secret Angel sizzled in a panty-baring Alexandre Vauthier navy blue gown with thigh-high slit, which she took full advantage of.
DAYUM! No wonder she made a pretty penny last year!
A matching navy leather jacket, strappy Giuseppe Zanotti heels, Kimberly McDonald jewels and a spiky Christian Louboutin clutch finished her hawter than hatwt look.
