Tish Cyrus, who just launched season four of her "Sorry We're Stoned" podcast with daughter Brandi, says Miley is thriving in her relationship
"He's cute," Tish tells PEOPLE, adding that she's never seen her daughter happier: "I think it shows just by looking at Miley, her face and her smile at the Grammys and just everything about her that she's in an amazing place."
She continues with a laugh, "Miley is just so fulfilled in her life, and that everything's working out perfectly. That's all I'll say about Maxx!"
Tish, 56, and her eldest child Brandi Cyrus, 36, recently launched season 4 of their podcast Sorry We're Stoned, where they talk about everything from the family dynamic to Tish smoking weed, and, yes, Miley, who just won her first two Grammys: best pop vocal performance and record of the year for her hit "Flowers."
"Just honestly, again, I think it's so much about how she feel on the inside," Tish says, noting that Miley no longer drinks alcohol or smokes marijuana.
"I really don't know that I've ever seen her happier. So I think that's really just coming from within, and also has to do with growing up. She's 31, so she's just stepped into who she really truly is, and it is just working."
