Rapper LIL' KIM has recruited Miley Cyrus for her upcoming mixtape, Hard Core 2K13.

The collection of new music from the hip-hop star was originally scheduled to be released on Friday (29Nov13), but Lil' Kim took to Twitter.com that same day to apologise for the delay.

She wrote, "I just want to make U (sic) guys happy... Please standby. 3 bonus tracks included! I love U guys!"

Lil' Kim also shared a tracklisting of the mixtape, which includes collaborations with rappers JadaKiss, YoGotti, French Montana and Cyrus, who is featured on a song called Bad B**ch.

On Halloween (31Oct13), Cyrus paid tribute to her pal by dressing up in Lil' Kim's infamous breast-exposing purple ensemble from the 1999 MTV Video Music Awards.
