"We're gonna pretend we're at the club, and it's Patti LaBelle's birthday," the firey Philly-born singer told her dance partner Artem Chignitsey.

In a clip that showed the pair's practice session, LaBelle recalls how she specifically requested 50 Cent's 2003 chart topper "In Da Club" on her birthday. This week she decided to take it to the DWTS stage.

But during a Sunday rehearsal, she appeared to have injured her knee, putting their routine in jeopardy. "Nothing's gonna stop Patti but Patti," the "On My Own" singer confidently stated.

Monday night's performance proved she is unstoppable.
