Lady Gaga on 'So You Think You Can Dance': Tears, Advice, Job Offers

Guest judge Lady Gaga left her mark on "So You Think You Can Dance" on Wednesday (July 27) night, with her stilt-and-pantsuit ensemble, her passionate advice for the contestants, as well as her teary reaction to watching dancer Marko Germar perform to a Jeff Buckley song (not called "Hallelujah" for a change).

The song, Buckley's cover of The Smiths' "I Know It's Over," brought with it memories of mistakes she made when she was younger.

"I'm just so proud of you" Gaga said after Germar's performance. "You know, you really love to dance and I know your mom's here. There were so, so many things that I did wrong when I was younger and so many things that I wish I could take back, and I felt every moment of that through your dance tonight."

Gaga was also extremely impressed with Melanie Moore's footwork. "I would hire you tomorrow to dance on my tour all around the world," she said. "There is something so athletic and so passionate and so beautiful and you're such a star!"
