Miley Cyrus continued to make headlines Friday night after her performance at the KIIS FM Jingle Ball in Los Angeles.

The 21-year-old singer, who has been courting controversy since her August performance at the MTV VMA's, performed another racy routine that featured her tweaking against a 'bad' Santa, the Daily Mail reports.

Cyrus performed her routine, featuring songs from her newest album Bangerz, while wearing a pair of high-cut red sequin hotpants, a matching crop top, and strappy patent leather boots.

Cyrus tweeted about her special on-stage guest, featuring a photo of the two backstage in costume, which she captioned "Bad Santa. #KISSJIngleBall "

The unnamed man dressed in the suit played along with Cyrus as she performed, staring at her backside while she danced around stage, and drinking onstage.

Cyrus's performance also featured a latex-clad female dwarf dancer, whose breasts Cyrus groped during the act.

Cyrus has been nabbing headlines for her controversial appearances and performances since the August 25th VMA's. For that show, the singer performed her single We Won't Stop in a teddy-bear onesie, before shedding the outfit for a nude-colored latex bikini and a foam finger. She was then joined onstage but Robin Thicke, and as the two performed his hit song Blurred Lines, Cyrus twerked against the married singer's leg.

Her engagement to fiancé Liam Hemsworth was called off only a few weeks later.

Her music video for the single Wrecking Ball also courted controversy after the singer went completely nude for the video, spawning several imitations from other artists and stars, including Betty White.

The singer's last controversial appearance happened during the broadcast for the MTV EMA's in November. After accepting her award for Best Video Award for Wrecking Ball, the singer lit up a joint onstage.
