"So excited for @bjenner and Valerie," Caitlyn captioned a sweet snap of herself with both her son and grandson. "They named their adorable first child Bodhi. The first Jenner boy!! the name moves on :)"
Burt, 37, is Caitlyn's son from her first marriage to Chrystie Scott. Last October, the race car driver opened up about Caitlyn's transition on Australia's Today show, where he revealed that the two have bonded "more now than ever." Still, he said he doesn't watch Keeping Up With the Kardashians.
"I don't really associate myself with it much," he said about the hit reality show. "I don’t watch it. It's just not part of my life."
