Blake Lively Reveals Which Family Member Was With Her on Met Gala 2026 Red Carpet

Spotted: Blake Lively finding some much-needed help on the Upper East Side.

After all, as the Gossip Girl alum made her surprise appearance at the 2026 Met Gala May 4 in a billowing Versace gown, she had a very special family member help her up the steps of the Metropolitan Museum of Art in New York City.

Alongside a snap of William McAlpin holding the dress’ dramatic train, Blake wrote on her Instagram Stories May 5, “My sweet angel gorgeous cousin.”

It was a look to remember for the “Fashion Is Art” dress code as the 38-year-old—who donned a colorful halter ballgown adorned with lavender crystals and Venetian Rococo-inspired hues on the skirt—needed four people to guide her up the stairs. (See all the celebs at the Met Gala here.)

But William wasn’t the only one of Blake’s family members on the actress’ mind during the biggest night in fashion. In fact, she paid homage to her and husband Ryan Reynolds‘ kids James, 11, Inez, 9, Betty, 6, and Olin, 3, with a very special purse.
