In a case of "Where are they now?" TMZ has found what former R&B sensation Sisqo has been up to.

The Dru Hill frontman and solo force behind the 'Thong Song' has downsized his performance area considerably since his last success in the early 2000s and is now playing tiny bars.

TMZ has video of the singer performing in a meager sports bar in Alexandria, Va. It's a sad state of affairs as Sisqo has to literally dodge and weave his way around the bar's waitresses and security.

Back in 1999, his 'Enter The Dragon' album peaked at No. 2 on the Billboard 200 Albums chart and went on to sell over 5 million copies in the U.S. His 2001 follow-up, 'Return of Dragon,' only sold a paltry 1 million copies.
