Blake Lively's unexpected reason for major wardrobe malfunction during It Ends With Us tour

Happy It Ends With Us day to all who celebrate! The much-anticipated flick has finally hit UK cinemas as of today (9 August).

In the lead up to the release, fans have been admiring the fashion choices of the star, Blake Lively.

36-year-old Lively portrays Lily Bloom in the flick, which is based on a Colleen Hoover novel of the same name.

The film, which explores the effects of domestic violence within a marriage, is set to be one of the buzziest films of the year.

Prior to the film's release, impatient fans haven't had much to go on, instead gluing their eyes to Lively's outfits at press events.

At a New York meet and greet, a Versace look worn by Lively has gotten everybody talking.

On Monday (5 August), Lively stepped out wearing a see-through beaded top, a pair of embellished jeans and Versace briefs.

However, the Gossip Girl star actually repeated a Versace outfit twice in two days - and made a shock admission.

She told reporters: "I wore this yesterday. But I wore my underwear inside out.”

She continued: "So I wore it wrong and I can’t do that to Versace.”

The first time she wore the outfit, on Sunday, the Versace band appeared black - but when worn the right way, it's pink.

Lively joked that her fashion mishap needed a 'round two' as it was 'disrespectful' to have worn it wrong.

She added that she was in 'a hurry' when dressing the first time - which explains it all.

Being the good sport that she is, Lively rewore the outfit - the right way. And she is clearly loving Versace right now.

On 6 August, Lively turned heads at the New York premiere which she attended alongside her husband, actor Ryan Reynolds.

Lively wore the iconic Versace gown that Britney Spears wore in 2002, and paid homage on her Instagram Story.

Lively wrote: "The ultimate queen who made us all want to sparkle and write and share our stories. Britney, us millennials all have a story of a moment or of years that you made us want to shine and inspire awe, with strength, and joy and immensely hard work.

"Thank you for your example and your contribution to women telling their stories. So excited about your biopic and all you have to come."

On the red carpet in NYC, Lively gushed to a reporter from Extra: "Britney Spears has meant so much to me forever. I'm a forever Britney stan.”
