Mojo had her mojo working on last night's Joe Millionaire.

As for Alison -- well, be careful what you wish for, you just might get it.

MoJo (alias Melissa Jo) and three other women will hang around the old French chateau for another week, trying to win the heart of faux millionaire Evan Marriott -- while unlucky-in-love Alison got the boot on last night's episode of the popular Fox reality series that has everyone talking.

MoJo, Sarah, Zora and Melissa M. all passed the test after romantic (and, yes, often stilted) dates in Paris with Evan, who's passing himself off as a newly minted $50 million man -- but is really a low-five-figure construction worker who sounds an awful lot like dumb-as-nails David Puddy from Seinfeld.

As for Alison, well, she and Evan cruised on the Seine -- but something just wasn't shipshape with the couple. Evan said he could tell they "weren't connecting," while the redheaded Alison thought her wannabe knight-in-shining-armor was a bit rusty around the edges. And she just couldn't come to grips with the fact that Evan says he's a meat-and-potatoes guy. What kind of millionaire eats hamburgers?

So, it was the old heave-ho for Alison, even though she had second thoughts, even after confessing to Evan that she wasn't all that interested in him. But it was too late: Evan awarded his more romantic damsels with necklaces, while Alison wept quietly, regretting her honesty in the face of all those (faux) millions.

As for sultry Zora, cunning MoJo, bubbly Melissa M. (who babbles on incessantly about being "a princess") and stunning Sarah, they all glowed with the shine of knowing they'll each have at least one more week to show their faces on national television -- and maybe bag a millionaire in the process.
