Theo Wenner, out. Benji Madden, in? Perhaps, when it comes to the love life and times of Miley Cyrus.

While the corpse of Cyrus' relationship with ex-fiance Liam Hemsworth is barely cold, the singer has taken to reaffirming that music comes first for her and that her career is like her relationship and is the ultimate priority. Then she was rumored to be dating Rolling Stone photog Theo Wenner.

Now, sources claim she hooked up with Good Charlotte's Benji Madden at Hollywood's Bootsy Bellows on Halloween night.

Insiders say Cyrus, who dressed as Lil Kim circa 1999, complete with a boob out and a purple pasty-covered nipple, arrived with 10 female pals and was in the mood to partay. What started out as a GNO – girl's night out, sucka! -- evolved into a hook up with the rock guitarist, who once dated celebutante Paris Hilton before she was trying to reinvent herself as a DJ!

Sources say that the Cyrus and Maden had a makeout sesh and even exited the club together, along with a group of pals.

Is it us or does every Miley Cyrus headline involve her tongue in some way or another? Just sayin'.

More to come…
