Blake Lively channels Britney Spears at movie premiere with Versace dress

Here is Blake Lively channel Britney Spears at her film premiere… with a nod to one of the singer’s most iconic looks.

Blake turned heads at the New York premiere of ‘It Ends With Us’ on Tuesday … in a single-strap Versace dress once worn by Britney herself.

The tribute to Britney follows the news that Britney’s best-selling memoir is on its way to being turned into a biopic.

As we first reported…Britney’s got the last word about who plays her in the film… which makes Blake’s fashion choice here even more interesting.

Before Blake, Britney slipped into this costume in 2002 at a Versace show in Milan, Italy.

Blake told Additional the dress means a lot to her because Britney meant a lot to her as someone who represented love, beauty, youth, hard work, determination, strength, sexuality and delicacy.

And listen… Blake says that when the dress became available, she knew she had to have it and had been waiting for the perfect time to pull it out of her closet for six months.
