But she's not the first starlet to wear the green Gucci frock. Kim Kardashian wore it last month at the Midori Parlour event in Los Angeles!
Tamara opted for a longer version but still managed to show a whole lotta leg... and plenty of cleavage too!
She paired hers with a black clutch, strappy heels and big hair before posing on the red carpet.
Kim K worked the plunging neckline too, teaming her dress with gold sandals and minimal accessories.
Her glossy locks were worn to one side for a suitably sexy take on the look.
They've both got the killer curves but who stole the style crown in this emerald frock? Let us know by voting in the poll below.
