You'll Be Mad for Selena Gomez and Benny Blanco's Alice in Wonderland Halloween Costumes

Selena Gomez and Benny Blanco went down a rabbit hole to find their perfect couple's Halloween costume.

The two dressed up as Alice and the Mad Hatter from Tim Burton's 2010 live-action movie adaptation of Alice in Wonderland, as seen in photos the Only Murders in the Building actress shared on Instagram Oct. 26, five days before the holiday.

Channeling Mia Wasikowska and Johnny Depp's characters, respectively, Selena sported a blonde wig with a black hair ribbon, an off-the-shoulder, pale blue, tulle dress and chunky white heels with black tips. Benny wore a poofy, curly red wig, a black top hat and clown-like makeup, plus a mismatched suit with a tan jacket.

Quoting one of Alice's lines from the film, Selena captioned her post, "Curiouser and curiouser.."

This marks the first time the "Come and Get It" singer has debuted a Halloween couples costume and comes more than a year after she and the record producer began dating.

Selena, 32, shared photos of their whimsical looks two days after they stepped out for a date night at the Rare Impact Fund Benefit in Los Angeles. Benny, 36, did not walk the red carpet with his girlfriend. However, the pair remained close inside the event and also showed PDA.

While the two have yet to make their red carpet debut as a couple, Selena has often brought her boyfriend as her date to celebrity events, such as the 2024 Emmys.

The two privately began dating in July 2023 and went public with their romance the following December. "He is my absolute everything in my heart," Selena wrote on Instagram at the time. "Why has he been the best thing that's ever happened to me?"

In May, after host Howard Stern told Benny that he's "predicting marriage" for him and Selena, the songwriter replied, "You and me both."

He publicly professed his love for the singer again on social media last week. On an Oct. 22 TikTok video showing a throwback clip of Daryl Hall singing the lyric "It's you and me forever" while performing "Sara Smile" with then- Hall & Oates bandmate John Oates, Benny wrote, "Me to my girlfriend a million times a day."
