Dancing twin sisters Yony and Zony have made their second appearance on the Ellen DeGeneres Show in less than week.

Dressed in blue motorcycle helmets, denim vests, magenta tutus and colorful stockings – they performed a dance routine to Justin Bieber’s “Baby” with Ellen’s guest DJ tWitch! on Tuesday.

The two first appeared on Ellen’s show last Thursday.

The twins shot to fame here in Taiwan after a video of them dancing to South Korean girl group Crayon Pop’s song “Bar Bar Bar” dressed in scooter helmets and tutus was posted on YouTube in February.

The video has since gained over 1.6 million hits on YouTube.

The two girls will also visit Hollywood and Disneyland during their U.S. trip.
