Miley Cyrus has been an open book when it comes to her sexuality — including her recent relationship with Victoria's Secret model, Stella Maxwell.

The duo have become so serious with one another over the last few months, in fact, they're actually talking about taking the next step in their relationship, Life & Style has learned.

"Miley's told friends that Stella is the one," shares an insider. "And she wants to make a huge statement with an over-the-top wedding in the fall!"

Miley, 22, and Stella, 24 — who met on Instagram shortly before the former Disney star split from former beau, Patrick Schwarzenegger, in April — aren't afraid to show a little PDA, either. As TMZ reports, they were recently kissing!

"Miley can't stop talking about how in love she is and how she wants the world to know," said the source, who added she wants their wedding to outshine Kim Kardashian and Kanye West's. "She's never met someone like Stella before and doesn't want to lose her."
