Miley Cyrus reportedly kissed Benji Madden at a Halloween party.
The 'Wrecking Ball' hitmaker - who ended her engagement to 'The Hunger Games' hunk Liam Hemsworth in September - was reportedly spotted cosying up to the former Good Charlotte star at Ciroc's costume party hosted by Adam Lambert at West Hollywood hotspot Bootsy Bellows.
A source told MailOnline: "They seemed really into each other. Soon they were flirting and talking very closely. Then they shared a kiss. They left Bootsy Bellows together around 1am.
"They tried to be discreet by sharing a car with some other friends but it was clear they were leaving as a couple."
Benji, 34, previously dated Paris Hilton, while the socialite's one-time best friend Nicole Richie is married to Benji's brother and former Good Charlotte bandmate, Joel Madden.
Miley turned heads on Halloween in a provocative Lil' Kim costume, which saw her sport a purple wig and one-shouldered jumpsuit that exposed her entire left breast.
