What does American Idol’s Haley Reinhart have that Stefano Langone doesn’t? Apparently a vagina. Idol judge Jennifer Lopez, sent a clear message to fans: No more girls! That put Stefano and Jacob Lusk on the bubble.

Paul McDonald, exited last week, the first guy to get the ax following departure of five girls in a row, leaving only two in the Top Seven. Jennifer was not happy.

“I’m hoping it’s not a girl,” she interjected.

Sure enough, when the bubble popped, Stefano was gone after more than 52 million votes cast. (Actually fewer than last week.)

The fans have been fickle on this year’s show, even as the judges have been mostly effusive.

Oddly, fan favorite Scotty McCreery got roughed up by Randy Jackson and Aerosmith frontman Steven Tyler. Yet he not only escaped the bottom three (again), but also was the top vote getter, according to DialIdol.

With the contestants now whittled down to six — McCreery, Reinhart, Jacob, Casey Abrams, James Durbin, Lauren Alaina — there’s nowhere to hide.

“I always hate this part,” said host Ryan Secrest, as he prepared to announce the results.

“Haley is safe!” he said. Given the fate of female contestants, even she doesn’t seem to believe it. “I’m safe?” she said incredulously.

It’s easy to understand her surprise. The talent is so thin on this year’s show any of the contestants could land in the bottom three and be eliminated, without as much as a whimper of protest, Pia Toscano notwithstanding, of course.

The mediocre level of talent was put on painful display when Reinhart, Alaina, Lusk and Langone butchered Train’s “Hey Soul Sister.”

Sure, it’s a tough song to sing, but this Idol crew didn’t come close.

Durbin, Abrams, and McCreery didn’t do much better; they manhandled Coldplay’s “Viva la Vida.”

It’s hard to believe this is the best American Idol could do this year.

So here’s where things stand: McCreery is the one to beat. Durbin, the only real contender, seems to have the chops to be a spoiler.

Casey is the darkhorse. He seems to resonate among tween girls, who are likely doing most of the voting. Advice: keep rocking, Casey!

Alaina should have been eliminated instead of Pia. But Pia was just a little too full of herself, and undoubtedly drew the wrath of tweeners for being too much of a high school queen.

Lusk lacks a fan base where it counts, among younger viewers. But oldsters are apparently keeping him in the race.

Haley deserves far more credit than she’s getting. Mean girl voters seem to have it out for her. Be humble Haley, very humble. Don’t piss off the tweeners, and you may have a chance.
