Miley Cyrus interrupts Z100 Jingle Ball backstage interview for shameless deodorant sponsor plug

She's renowned for her on-stage antics but Miley Cyrus' actions backstage are just as bizarre.
Miley, 21, was backstage at Z100's Jingle Ball 2013 at Madison Square Garden on Friday and stopped to apply AXE deodorant in a strange plug for the brand which sponsored the interview area.

The Wrecking Ball singer struck a series of unusual poses as she applied the antiperspirant, but kept up a conversation with those around her the whole time.

For once the controversial singer kept her clothes on and Miley was quite covered up on the red carpet.

The blonde beauty wore tailored black trousers with a distinctive yellow stripe down the side and a sleeveless white shirt.
Her black bra was visible through the shirt.

Miley also performed at the event and was introduced by her friend, troubled actress Lindsay Lohan.
Before the event, Lindsay posted a picture of herself on Instagram and wrote: '#jingleball2013 #Z100radio @mileycyrus can't wait to announce a talented beauty (sic). '

Lindsay went all out for the occasion in a sequinned white T-shirt, over tiny black shorts and thigh high leather boots.
She left her long red hair loose around her shoulders and was spotted laughing and smiling during an interview with iHeart Radio.
