FORGET about bros before babes! “Twilight” hunk Kellan Lutz, a good friend of Liam Hemsworth, is having a fling with Miley Cyrus, a source confirmed to Us Weekly magazine.

Cyrus was also spotted embracing Lutz while giving him a kiss on the cheek at a party Friday night.

The actor, 28, reached out to the “Bangerz” singer, 21, in early December, said the insider. “The next day, they hung out. And they’ve been hooking up ever since.”

Cyrus even invited the 185-cm actor on an overnight jaunt from Miami to the Bahamas on Dec. 17. Rumors of a potential romance between the two were ignited after both stars were photographed walking off the same private jet, separately, after returning to Miami from the excursion.

Lutz, who said he “got cut” to film January’s “The Legend of Hercules,” is a “nice eye candy” for the singer, the insider said. “It doesn’t hurt that he’s Liam’s pal,” the source continued. “They really enjoy each other’s company.”

Cyrus and ex-fiance Hemsworth split back in September after three years together. “I just believe that when a chapter is done, you have to close it and start that new one,” the hitmaker told Ellen DeGeneres one month after the couple announced their broken engagement. “That’s kind of where I am right now. I felt like I have so much to be thankful for at this time that my energy hasn’t really been focused on that.”

Up next for the “Adore You” crooner? Cyrus will perform live at Times Square on New Year’s Eve, right before the ball drops.(SD-Agencies)
