Been there, done that ... won that — Melissa D'Arabian's back on Star tomorrow night, and I'm eager to hear any advice she may have for the finalists.

As someone who knows what it takes to hang tough in this competition, she's the perfect person to help these guys stay motivated. And her direct, no-nonsense approach may be just what they need at this point in the race. Here, listen to her share a key belief she feels is essential for scoring a win.

An added bonus: Melissa's joining us for an encore appearance in tomorrow night's Star chat. Catch up with her at 9pm/8c! (Can't make it? Post your questions for Melissa here.)

P.S.: For any of you who may be wondering just how good her Ten Dollar Dinners really are (or if ten bucks will really get it done), I'm here to tell you that my experiences with her recipes, eight so far, have been excellent. Last week, I made her Lemony Shrimp Scampi Pasta and it was just fantastic. A light, summer-perfect dish that only cost ten dollars. (All right, $10.47, but that still counts.)
