Solange, Beyoncé and Becky at the Met Gala

Rita Ora is Not Becky. Katy Perry is Not Becky. And Solange Knowles says she was throwing shade at a pink cartoon character after the 2016 Met Gala on Monday night.

We believe two out of three.

"Shout out to when you think you all 'artsy and [expletive]', but your just rude and annoying lol," Solange tweeted around 2 a.m. in what was interpreted as a slam against someone she'd crossed paths with at the event or one of its after-parties.

As the headlines spread Tuesday and a Twitter follower wondered, "for who is this tea?? damn girl," Beyoncé's sister chose to pin it on a lead character from a Nick Jr. animated show.

Uniqua, who does rock some serious pink-on-pink polka-dot overalls and is in fact a star of "The Backyardigans," was almost certainly not at the Met Gala on Monday night. Hmm ...

Perry, meanwhile, was rocking a "Not Becky" name badge at an after-party, despite not being among those named as Jay Z's alleged side chick in the hubbub following Beyonce's "Lemonade" release.

And Rita Ora, who went out of her way last week to declare Rita-is-Becky rumors false, reinforced that sentiment as she rocked out on the dance floor with an identical "Not Becky" badge after dazzling on the red carpet earlier in the night. She took a party selfie with Beyoncé and labeled the shot "family."

Did we mention the party was at the Standard High Line, where Solange and Jay Z got into it after last year's Met Gala? Yeah, it was. Though Jay Z was nowhere to be seen.

And as for the main woman to say she's not Becky: Rachel Roy -- who attended this after-party last year -- was posting on social media Monday about overalls. Fortunately, no pink-on-pink polka dots were mentioned.
