After calling off their engagement nearly two years ago, looks like Miley Cyrus and Liam Hemsworth have completely moved on from each other.

The pop star, who came out as bisexual in an interview with Paper magazine, has lately been showing off major PDA with Victoria's Secret model Stella Maxwell.

The two girls were first spotted making out in public on June 30 on the set of Cyrus' new music video. TMZ reported at the time that they "constantly kissed, caressed, held hands, and Stella got very comfortable on Miley's lap."

The duo then dined together at Cocina Condesa in Studio City on July 6.

"They could not keep their hands off of one another," an eyewitness told Us Weekly, adding that they were "whispering into each other's ears, laughing, smiling, and genuinely having a good time together."

Cyrus and Maxwell were also seen holding hands and grabbing drinks together in Malibu earlier this week, as E! reported.

Does Hemsworth have any issues with his ex-fiancée's new romance?

"He is aware, and nothing surprises him anymore with Miley but he is not heartbroken, he has moved on," a source revealed to Hollywood Life. "But he is aware of the hookup."

Meanwhile, the "Hunger Games" actor has been romantically linked to his "Independence Day 2" co-star Maika Monroe.

According to OK! Magazine, via CelebDirtyLaundry, the couple has been very close to each other on their movie set.

"Everyone has noticed their mutual affection," an insider claimed. "Maika is sweet and down to earth, and has a zero drama personality, something Liam was attracted to instantly. Liam thinks Maika is the coolest girl he has ever met."

Also, Hemsworth and Monroe were spotted getting cozy at a Fourth of July party thrown by director Roland Emmerich.

"His hands was on her butt as she was grinding into him and they were making out at the bar," a source told Us Weekly. "Liam was draped all over her. It was so PDA and in-your-face."

However, Cyrus reportedly does not care about Hemsworth's new relationship, since she has moved on and is too preoccupied with her new girlfriend.

"Miley heard about them hooking up and she has no problem with it," an insider told Hollywood Life. "She thinks Maika's hot -- she's like, 'High-five, Liam!' and Miley's busy with Stella right now, so she's not worrying about it."
