Flawless deja vu!
Britney Spears may LURVE her sweats when she's running errands, but when it's time to clean up, SHE CLEANS UP!!!
Her beaded sparkly Michael Costello gown featured a sexy plunging neckline showing off some nice side boob and a dramatic sweep train!
If you'll recall, Brit-Brit had a comparable look at Elton John's Oscars party last year! Similar sparkly dress and gorgeous brunette locks!
The dress was also reminiscent of one that Beyoncé wore to perform at her Glasgow concert.
Icons have exquisite taste!
