She’s 18 now – and while her rapper beau Tyga has previously denied including Kylie Jenner in his (often explicit) lyrics… it seems her milestone birthday is about to change all that.
The 25-year-old musician is currently working on new material; and the content of one particular track – Stimulated – is certainly raising eyebrows.
One line includes: "They say she young… I shoulda waited… She a big girl, dawg… When she stimulated."
The same song furthermore includes a reference to "penetration."
Of course, we don’t know for sure that he’s definitely referring to the teenage TV personality, but it’s certainly seems probable – not least as the duo have been romantically linked to one another for at least a year.
Since celebrating her birthday earlier this month, Tyga and Ms Jenner have taken their union to the next level: on a recent sun-soaked trip to St Barts in the Caribbean, the duo put on numerous PDAs – something they very much avoided while she was still underage.
It’s not the first time that his explicit rhymes have been linked to reality TV’s most famous family either.
In a previous song, Pleazer, Tyga rapped about vagina juice, getting prosecuted for having sex with a minor, and Kardashian pu**y. Although he later insisted the track was NOT about Kylie, but some other random woman.
It has been reported that the rapper’s most recent musical offering, The Gold Album: 18th Dynasty, bombed in terms of sales.
It was due to be released last December, but numerous delays and issues meant it only emerged in June.
18th Dynasty subsequently failed to even break into the Top 200 in the US, and supposedly has shifted a wholly modest 25,000 copies.
Tyga has previously said on Twitter that he’s not bothered by the album’s apparent poor sales performance – claiming he was always more focused on success via streaming platforms such as Spotify.
Still, it would hardly be surprising if he decided to start including his much more famous girlfriend in his lyrics: after all, the publicity alone would be invaluable.
And while he's showering her with impressive gifts – including a €300,000 Ferrari (which Kylie then had altered last weekend) – friends have claimed that he's living widely beyond his means.
"He's holding out for a major reality TV show with Kylie, or another lucrative deal on the back of their relationship," one associated recently offered.
"Tyga recognises that he's racking up debt at the moment, but he's confident with Kylie now 18, they'll be inundated with six- and seven-figure offers over the next few months."
Last week, it was reported that Ms Jenner was offered an astonishing €9m by Vivid Entertainment – if she wanted to do porn.
