Blake Lively Explains Britney Spears Re-Wear at ‘It Ends with Us’ Premiere (Exclusive)

Blake Lively stunned on the red carpet for the NYC premiere of “It Ends with Us" on Tuesday, getting support from hubby Ryan Reynolds and his “Deadpool & Wolverine” co-star Hugh Jackman for her big night.

“Extra’s” Mona Kosar Abdi spoke with Blake, who explained her very special look — she wore Britney Spears' iconic 2002 Versace butterfly dress!

She said, “This dress meant so much to me because of what she meant to me. Like, she was just somebody who represented, like, love and beauty and youth and hard work and determination and strength, and she was in touch with her sexuality and her delicacy and she just sort of represented it all.”

Referencing Britney’s memoir “The Woman in Me,” Blake added, “Her telling her own story, the way she did and the way she’s about to with her biopic, it just like, I don’t know. Britney has just meant so much. I’m a forever Britney stan.

“When this dress was available, I was like, ‘Yes, I need it’ and I’ve had it, you know, for almost a year now and I’ve been saving it for this... six months."

Along with doing press for the movie, Blake has been promoting new hair care line Blake Brown Beauty. She admitted, “It’s been a crazy week. I haven’t slept in, like, a lot of time.”

Standing in front of a UrbanStems floral arrangement, Blake gushed about her family’s amazing summer between “It Ends With Us,” “Deadpool & Wolverine,” and the hair care line. She reflected, "I keep looking around going, like, 'Remembe these moments.' Like, these are the moments at the end of your life where you're going to look back and say, 'Wow, how beautiful my life is.' I'm very present and I'm very grateful."
