Miley Cyrus, Benji Madden kissing? 'Bangerz' twerker 'hooks up' with Good Charlotte rocker at Adam Lambert's wild Halloween party [PHOTOS]

Apparently, Bangerz songstress Miley Cyrus is enjoying the single life!

The 20-year-old twerker attended Adam Lambert's Halloween Party Powered by CIROC dressed as Lil Kim over the weekend... and while there, she ended up hitting it off with former Good Charlotte rocker, Benji Madden.

A fellow partier tells the Daily Mail, "They seemed really into each other." The duo was allegedly spotted kissing later on in the evening.

Another onlooker reveals, "Soon they were flirting and talking very closely. Then they shared a kiss. They left Bootsy Bellows together around 1 am... They tried to be discreet by sharing a car with some other friends but it was clear they were leaving as a couple."

A source for HollywoodLife.com continues, "The hookup 100% happened as they met each other that night, so the sparks flew instantly and they for sure went home together, so draw your own conclusions from that..."

Still, there's probably nothing too serious going on between Cyrus and Paris Hilton's ex... another insider explains, "The way that they were together I would imagine there is some life to this, but only time will tell... Miley is having fun and not looking into another relationship. Plus, Benji is kind of a man whore." 

Meanwhile, a so-called friend friend recently told People magazine, "Nothing happened between Miley and Benji. After being introduced at the club, they chatted but it wasn't romantic. They left the club with a group of people and went to a house party. Miley and Benji had fun together, but they didn't hook up."

In fact, Cyrus spent most of the night dancing and smoking with party host Adam Lambert... allegedly.

Well, well, well... what do Mstars readers think?
