Though up until now, her little sister Noah Cyrus, 18, has been relatively controversy-free.
However, after confirming her romance with 21-year-old rapper Lil Xan, Noah’s fans have gone into meltdown online.
The duo have been sharing various loved-up snaps of themselves, with Stay Together hitmaker Noah posting her first snap of them to her 4million-strong Instagram army just yesterday.
Dressed in a black boob tube and white cap, Noah gave a sweet smile for the camera as Lil Xan planted a kiss on her cheek.
She captioned the shot: “OK for real. Look at this lil nuggetttt!!! [love-heart eyes emojis] also we both so sad it’s so sweet.”
Lil Xan, real name Diego Leanos, may not be a big name here in the UK just yet but is rising up the notoriety ladder Stateside.
The rapper is known for his breakout hit Betrayed in which he sings about his relationship with prescription drug Xanax.
In light of his dependency on it for two years, he now urges people to get clean like him.
Lil Xan is of course also known for his array of tattoos, many of which are on his face.
He recently shared his latest etching on Instagram, eight black dots inked on his nose.
Alongside the pic, he wrote: “New tattoo inspired by Prince X! Legends never die and energy lives forever.
“Rest in peace to X Peep and everyone that’s after.”
Within minutes of Noah’s post being online, it was flooded with messages from fans – not all of which were positive.
“You know u can do better right?” one follower replied.
Another added: “OMG are they dating? Those would be some scary babies.”
“Okay this needs to stop,” a third replied.
A fourth moaned: “The joke is over.”
Meanwhile, others were loving the bizarre coupling.
“You two are so cute together,” one supporter gushed.
“Can I come to the wedding,” another added.
A third continued: “This is everything.”

Meanwhile her track My Way, built on her UK fanbase, made its way to number 76 in the UK chart.
