Miley Cyrus and Liam Hemsworth are heading to splitsville.

According to a Page Six report, Hemsworth was busy canoodling with another woman at the Toronto Film Festival, spies said.

On Saturday at LDV Hospitality’s pop-up club Bungalow 8 on the Thompson Hotel rooftop, spies saw Hemsworth "locking lips with a random brunette." Later, "they left together."

Multiple sources confirmed his smooch with the mystery woman. But Hemsworth’s rep insisted: "There is no truth whatsoever to any of this."

Earlier this week, Cyrus was romantically linked to her music producer, Mike WiLL Made It. According to Star Magazine, she allegedly "hooked up with" the hit record producer.

On Wednesday, Media Take Out reported the gossip, adding that the pair were first introduced in February to work on Miley's fourth album, Bangerz.

Cyrus and Mike WiLL Made It, who has produced songs for stars like Rihanna and Jay Z, have reportedly "grown close after long hours spent n the studio, with no attempts to cover up their budding romance."

"Everyone knows they're hooking up," an insider revealed in the Star report.

The new dating rumors come on the heels of numerous reports that Cyrus' fiance is hoping for a "clean break" in their relationship. According to a source close to the actor, the pair is "just weeks away from calling it off permanently."

"He is over her and wants to make a clean break," the source told Us Weekly. "No more back and forth."

Hemsworth has reportedly decided to end the romance after Cyrus' 2013 MTV Video Music Awards performance, where she rubbed up against Robin Thicke and made crude gestures with a giant foam finger. He thought it was "mortifying," the source revealed.

The stars met three years ago on the set of their film The Last Song. They got engaged in the summer of 2012.
