“My drummer baby,” the Almost Famous alum—who kickstarted her own music career two years ago—wrote in a 2023 birthday tribute for Bing. “From the first time he played the kick drum, to his smoother pre-teen drumming ways. He plays the drums like he walks through life, sharp, vibrant, caring, dedicated and always perfectly wild and unpredictable!”

But Bing isn’t the only child of Kate’s to show her some red carpet support as of late. Last month, Ryder was by his mom’s side as they attended the 2026 Vanity Fair Oscars party together.

The two posed for photos at the event, showing off their coordinating black outfits. And before going inside to the party, Ryder had some kind words to share about his mom, who was nominated for Best Actress that night for her role in Song Sung Blue.

“I’ve never been more proud of my mother,” he told Entertainment Tonight. “I have to say, I’ve seen my mom close up more than anybody…put in more work and more dedication and more time than I’ve ever seen in my life. And it’s just such a beautiful thing.”
