VIDEO: 'Lesbian' Duo tATu Performs at Winter Olympics Opener

Members of Russian pop duo tATu (best known in the U.S. for their 2003 hit "All the Things She Said" (and for kissing and pawing each other during nationally televised performances)), who are perhaps most-remembered for kissing each other onstage during performances in the early 2000s, put on a show Friday at Fisht Olympic Stadium before the Winter Olympics opening ceremony in Sochi, Russia.

Lena Katina and Yulia Volkova of tATu held hands while singing, and the moment caused "Tatu" to become a worldwide trending topic on Twitter. 

The choice to have tATu perform raised eyebrows because of what's been described as their "pseudo-lesbian" behavior (which some saw as simply as an attention-grabbing stunt at the time).
