Why pop superstar crashed a talk show after months out of sight

Ariana Grande is back. The pop star, 33, made a surprise appearance on The Tonight Show Starring Jimmy Fallon on Sunday, Nov. 8, her first TV appearance since she stepped away from the public eye.

She didn't come alone. Grande walked out with her Focker-In-Law co-stars Robert De Niro, 83, and Ben Stiller, 60, People reports.

The trio cut in as Fallon was saying the holiday spirit made him want to sing, and gave him a rendition of "O Christmas Tree".

A whole new look

Fans noticed the hair first. Grande debuted a shoulder-length, chocolate brown bob, flipped at the ends and parted on the left, WWD reports. Her stylist, Brandon Pietsch, also works with Megan Fox and Rosé. She first showed the cut on Instagram in late October.

She wore a black Givenchy suit by Sarah Burton, from the Spring/Summer 2027 collection: a slightly oversized, double-breasted wool blazer and matching cigarette pants, with pointy suede heels and a velvet choker, Harper's Bazaar reports.

Law Roach styled the look. Her makeup was rosy and glittery, with a glossy pink lip, a powder-pink manicure and tiny gold hoops.

It's a long way from the hair fans know her for: ginger on Victorious, the high ponytail of the 2010s, then three years blonde as Glinda in Wicked.

Why she stepped back

On Aug. 2, a representative told People that Grande "will be taking a step back from visibility after she completes the Eternal Sunshine Tour." People reported that it came amid intensifying scrutiny of her health and body.

The rep said she "looks forward to finishing the tour and ending it on a high note, both healthily and happily." It added: "She loves her fans and has loved every minute of this tour so much."

The next night, Grande addressed it on stage. "The announcement that was made yesterday was not a reactive or impulsive thing," she said, explaining it had been planned "quietly, a long time ago." She called the tour "one of the most healing, beautiful, correct and special experiences" of her life.

The tour wrapped in London on Sept. 1. She has also pulled out of the West End revival of Sunday in the Park With George at London's Barbican Centre, where she was due to star with her Wicked co-star Jonathan Bailey.

On Fallon's couch, Grande said she was "so honored" to be asked to be in the film and "fell in love" with the script.

The trio also performed a skit called "My Family's Money" and played True Confessions, where she convinced the others she once fell into a tank at an aquarium in Boca at age 4, Parade reports.

Focker-In-Law, the sequel to 2010's Little Fockers, opens in theaters on Nov. 25.

Grande plays Olivia Jones, a hostage negotiator who is set to marry Henry, the son of Stiller's character.
