Elton John and Chappell Roan turned his annual Oscars watch party into their own “Pink Pony Club” … performing some of their biggest songs together for a good cause … and it’s all on video.

The “Rocket Man” and the “Pink Pony Club” singer collaborated Sunday night at Elton’s annual Academy Awards watch party, which benefits his AIDS Foundation.

Elton and Chappell grabbed the mic and hit the stage to perform her smash hit … with Elton belting out ‘PPC’ lyrics while wearing a pink cowboy hat.

Casey Anthony has a new gig — she’s now a self-proclaimed “legal advocate” and is promoting her role on her brand-new TikTok account.

The formerly acquitted defendant — who was on trial for murder in 2011 for her daughter Caylee Marie Anthony‘s death — explained that after being thrust into the legal spotlight, she’s turned what many saw as a curse into a blessing. She says her new goal is to give people a voice and the right tools when they find themselves in a sticky legal situation.

Casey used the video to reintroduce herself, saying she’d only be posting professionally, limited to legal matters, and that her drive to be a legal warrior really kicked off after seeing people she knows personally who were targeted and attacked recently. She doesn’t specify, but she mentions being a proponent for the LGBTQ community and for women’s rights.

The big winner at the Oscars was “Anora,” but Ben Stiller was more focused on something happening thousands of miles away on Sunday … the New York Knicks’ matchup against the Miami Heat.

Stiller was a presenter at the biggest night in Hollywood … experiencing a stage “malfunction” while announcing the Best Set Design category — an obvious ploy to get some laughs.

Despite having a big job in the festivities, it’s clear the “Severance” director wasn’t gonna let it get in the way of his diehard Knickerbockers fandom … as he sent out a celebratory social media post after New York narrowly beat Miami in overtime, 116-112.

It drew plenty of responses from users … who laughed at the thought of the actor decked out in a tux and rubbing elbows with the biggest names in film — but still keeping an eye on Jalen Brunson and OG Anunoby.

Stiller’s passion for the Knicks is no secret — he loves to hit up Madison Square Garden whenever he can … getting a spot right on Celebrity Row countless times.

Oh, for what it’s worth — “Wicked” ended up winning the set design category.
