What can we say? She's just being Miley.
In case you missed it, Selena did the imitation during her opening monologue, when she told the audience that she'd asked Miley (one of her "oldest friends" and someone who's hosted SNL multiple times) for some advice
"She said, 'Just be yourself and have fun,'" Selena said in her best Miley voice. "And I was like, 'Miley is that just an excuse for me to do an impression of you on the show?' And she was like, 'Hell yeah, I'm Miley Cyrus.'"
Miley showed her support on May 17 by sharing a video of Selena's performance. "HELL YEAH I'M MILEY CYRUS @selenagomez @nbcsnl," she wrote on Instagram alongside a picture of herself wearing a tank top with the same phrase.
In fact, they've supported each other over the years, and Selena appeared on Miley's "Bright Minded: Live" Instagram series in April 2020.
"I've always been a fan of yours," Selena said at one point during their chat. "I think you're one of the greatest singers ever."
