It's only been two months since Miley Cyrus split up with her ex-fiancé Liam Hemsworth, however, it seems the "We Can't Stop" singer may have already moved on to someone new, Good Charlotte rocker Benji Madden. 

According to E! News, sources say the 20-year-old singer was spotted making out with the 34-year-old musician Thursday night at the Bootsy Bellows nightclub. Cyrus attended the Halloween party at the West Hollywood hotspot dressed as Lil Kim and with a big group of girls. The singer spent part of the night hanging out with pal Kelly Osbourne and her fiancé Matthew Mosshart at their joint table.

"They were dancing and just really getting into the spirit of things," the insider told E!. "Kelly didn't stay very long and so after catching up with Miley she left."

However, the "Wrecking Ball" singer's night then spiced up when she ran into Madden. "They seemed really into each other," an eyewitness tells told MailOnline. "Soon they were flirting and talking very closely. Then they shared a kiss. They left Bootsy Bellows together around 1 a.m."

"They tried to be discreet by sharing a car with some other friends but it was clear they were leaving as a couple," the source adds.

Ironically, Hollywood Life reports that Cyrus was spotted hanging out with Madden's ex-girlfriend Paris Hilton, 32, just hours earlier at another party at Beacher's Madhouse in Hollywood.

Along with Madden, Cyrus has also been romantically linked with Theo Wenner, 26, after her breakup with Hemsworth. Miley met Theo when filming her sexy shoot for Rolling Stone, and they've reportedly been getting closer ever since.
