Brandi Cyrus, 32, addressd her sister's broken marriage head-on in a podcast called "Your Favorite Things," which she hosts with "Bachelor In Paradise" bartender, Wells Adams.
Sitting down with Adams on Tuesday, he asked about the photos showing Miley kissing Brody Jenner's ex over the weekend in Italy.
Saying his "podcast worlds are colliding" because he also hosts a podcast with Kaitlynn's "Hills" co-star Stephanie Pratt, he asks, "What is going on?"
That's when Cyrus' big sister responds, "Are you just jealous you're not apart of the whole thing?"
Brandi also includes, "The only think I am going to address is I ask people to respect our privacy while on vacation."
But that's not the only thing she said because she also stood by her sister when the split with Hemsworth was brought up.
"It's not my business to talk about and it's nothing anything of mine to tell," Brandi said.
"There's nothing I can really say. I just, I'm here for her, obviously, and I've been spending a lot of time with her," Brandi added. "When [Miley's] ready to talk about it or whatever, then she will."
As The Blast reported, Hemsworth and Cyrus announced their separation on Saturday after less than a year of marriage.
Shortly after, photos showing the bikini-clad singer making out with Kaitlynn surfaced.
Hemsworth commented on their breakup, saying he wished her nothing "but health and happiness going forward."
Brody Jenner weighed in on his estranged wife and Cyrus kissing, but cracked a joke about Hemsworth, to which Cyrus responded, "Go take a nap" and "cool off."
