Oscars 2025 Best Dressed: Cynthia Erivo, Zoë Saldaña & More Red Carpet Looks

You better belieb Hailey Bieber brought her fashion A-game on Oscars night.

In fact, the Rhode Skin founder dug into the archives and wore a 1987 Yves Saint Laurent dress to Vanity Fair's party celebrating the 2025 Academy Awards on March 2. (See all the Oscars arrivals here and click here for the complete list of winners.)

For the occasion, Hailey paired the strapless black gown with jewelry from Tiffany & Co., including statement-making earrings studded with over four carats of diamonds. To cap it all off, the 28-year-old had her signature blonde locks coiffed in loos waves by hairstylist Bryce Scarlett using Nexxus products.

While her husband Justin Bieber—with whom she shares 6-month-old son Jack Blues Bieber—opted to skip the red carpet affair, the two did do some celebrating at the "One Less Lonely girl" singer's 31st birthday party on March 1. As seen in an Instagram Story video, Hailey held up Justin's birthday cake as he blew out the candles.

And perhaps that will finally put an end to divorce rumors the pair have been facing in recent months, which were sent into overdrive in January when Justin's Instagram account unfollowed Hailey.
