Lauren Alaina fans are in an uproar -- worried she might get cut from "
American Idol" tonight ... because of the deadly tornadoes that ripped through the South last night.

Lauren's hometown of
Rossville, Georgia -- population 3,500 -- was devastated by the twisters ... leaving most homes without power, land lines, or mobile phone service.
Now Lauren's friends and family tell TMZ they're concerned because Lauren's main supporters couldn't see the show and weren't able to vote.
One friend said, "It would be a travesty if she was taken off the show because of an Act of God" -- and another added, "I do believe the weather should be taken into consideration when it comes to the voting."
One friend who was outside the damage zone tells us she voted more than usual for Lauren ... and made online appeals for others to do the same.
Will it be enough to get Lauren into the top 5?
One of the Top 12 finalists from last season's "
American Idol" had to escape through the window of a burning car Tuesday night ... when her GMC Envoy suddenly BURST INTO FLAMES.

25-year-old
Paige Miles -- who claimed 11th place on the show -- was on her way home from rehearsal in Florida ... when something went terribly wrong and her SUV caught on fire.
Miles, who documented the terrifying incident on her Facebook page, explained, "The electric shut down, the car
doors wouldn't open, i jumped out my window and watched my mother's
Envoy blaze."
Moments after she emerged from the fiery wreck, Miles said she was crying and shaking ... and her blood pressure was through the roof ... but she didn't seem to have suffered any major injuries.
Afterward, Miles took photos of the charred remains of her mom's ride -- pretty damn scary.
Jon Secada was so moved when he watched "
American Idol" contestant
Jovany Barreto perform one of his songs on the show this season ... he agreed to mentor the kid ... TMZ has learned.

TMZ spoke with Barreto -- a Top 24 finisher -- who tells us
he reached out to Secada after performing the Grammy winner's hit song "
Angel" ... hoping to get some feedback from his idol.
Jon told the kid he was impressed -- and offered to take 23-year-old Barreto under his wing ... "kind of like a mentor of sorts."
Jovany immediately moved to Miami to pursue the opportunity -- and Secada tells us there are plans in the works to record something together in the very near future.
Secada adds, "I think he's a very talented singer and can be a great asset to the music industry singing both in English and Spanish."
Steven Tyler has blown up even bigger because of "
American Idol" -- and he's making a big move, telling our photog yesterday he's gonna shoot a music video for a new song ... and no Aerosmith.

The music video shoot will go down Monday.
By the way ... Tyler has a memoir called "Does the Noise in My Head Bother You?" coming out on May 3.
Aero-who?

Jennifer Lopez waved to fans as she left a Best Buy in West Hollywood on Tuesday.

"
American Idol" does the 41-year-old mother of two's body good.
He's doing her, and now ... she's doing his show -- TMZ has learned,
Pia Toscano will be performing on "
Dancing with the Stars" next week ... and get this, her new BF
Mark Ballas will dance to her music.

It's been in the works for a while --
and an hour ago, the deal was sealed.
Pia's performance signifies a borderline incestuous cross-pollination between the two biggest shows on TV ... "
American Idol" and "Dancing."
And if that's not enough -- Pia will be back on "Idol" tomorrow for a special cast-off reunion.

Pia Toscano was a single woman two months
BEFORE coming to Hollywood in March ... and long before she started dating Mark Ballas ... TMZ has learned.

As we previously reported, Pia and Mark went out on a date the NIGHT AFTER she got the boot from "Idol" ... and have since ratcheted up their romance.
There's a report out that Pia unceremoniously dumped her caterer boyfriend
Carlos Nunez to trade up to Ballas.
But our "Dancing with the Stars"/"American Idol" spies tell us ... Carlos was history long before Mark entered the picture.
Check out the pics we got of Pia and her ex. Ah, what could have been.

American Idol" finalist
Jacob Lusk threw himself at the mercy of a court back in November -- begging a judge to end his probation from a 2009 arrest so he could compete on "A.I." ... TMZ has learned.

It all started back in February 2009 -- when cops cited Jacob for riding on an L.A. metro train without buying a ticket. Jacob blew off his court hearing and an arrest warrant was issued.
Fast forward to Nov. 2010 -- a day after Jacob auditioned for "Idol" and got his golden ticket to Hollywood -- Lusk was pulled over for a traffic stop. The cop discovered the warrant and arrested him.
Jacob went to jail and then to court the next day and pled no contest to
the train-hopping charge. He was sentenced to 3 days in jail and 2
years probation.
Jacob served his time and then went back to court, telling the judge
"Idol" wouldn't let him on the show if he was on probation. After his
emotional plea, the merciful judge terminated his probation.
Fun Fact -- On night one in the pokey, Jacob sang to
170 inmates, who liked it a lot. Thing is, the guard wasn't a fan,
screaming through the loud speaker, "This isn't a
f**king singing contest."
Undaunted, we're told Lusk sang over the next day-and-a-half, preparing for "Idol." And on his last day, Lusk sang a farewell
song, and another guard went on the loud speaker and said
it was "bad ass!"
UPDATE: Lusk tweeted this morning, "I've been through a whole lot more than folks would know in this lifetime...BUT GOD has KEPT ME...and I am so thankful! Be blessed!"
Getting rejected from "
American Idol" is bad enough -- but to add insult to injury, TMZ has learned, one ex-contestant also got shut down by OTHER "Idol" rejects ... after asking to join their reunion concert.

Sources connected with tonight's Minneapolis reunion show tell TMZ,
Dr. Chris Kammer -- a giant toothbrush-carrying dentist who was cast off early in the season -- contacted the show organizer and fellow reject
Caleb Hawley ... to see if they needed an MC.
Caleb wasn't into the idea -- and responded to Dr. Chris via email, writing, "Though I really appreciate your offer to MC, I think we'll hold this one down on our own."
Caleb offered to put Dr. Chris on the guest list for the show -- which also features Chris Medina and Carson Higgins -- but that wasn't good enough ... because we're told, Dr. Chris plans to protest in front of the venue before the performance.

Ashley Kauffman is sticking by her weight discrimination story -- saying she was told flat-out by an "Idol" employee that she was "too big and too heavy" to sit in the front row during last week's show.

Kauffman appeared on "
Good Morning America" this AM, where she explained how the whole ordeal allegedly went down ... and also took the time to correct a few parts of her story that are circling around that AREN'T true.
Kaufman admitted she WASN'T forced to sit all the way in the back of the studio -- more like six rows back from the stage -- and that she DIDN'T have to sit alone without her friends.
As we first reported, "Idol" honchos are calling BS on Kauffman, saying, "We always strive to assure that
every audience member has the best experience possible, and these
allegations are simply untrue."

Pia Toscano just boarded a plane at JFK airport in New York City -- she's coming back to L.A. for another date with
Mark Ballas.

Pia says she thinks we gave her good advice when she was in our office last week -- stand next to someone famous to fuel the rumor mill.
Pia and Mark hit it off so well during their date in L.A. on Friday, that Mark invited Pia back to the West Coast for
another round of tonsil hockey ... and
TO MEET HIS MOTHER.
No pressure.
