Aerosmith

Steven Tyler has entered a rehab facility due to an addiction to prescription painkillers -- this according to the Aerosmith front man himself.

The 61-year-old singer told People he became addicted to pain medication after suffering multiple injuries over the last 10 years of performing.

Steven, who was rumored to have quit the band, put it best: "There's absolutely no validity to rumor that

is breaking up, mutha f**ka!"

And there you have it.

What is Aerosmith without Steven Tyler?Joe Perry and some guys you can't remember the name of.

The unthinkable might be a reality -- Tyler may be on his way out. Joe Perry told the Las Vegas Sun he thinks Tyler has quit, but he isn't really sure.

He says, "Steven quit as far as I can tell ... I don't know anymore than you do about it. I got off the plane two nights ago. I saw online that Steven said that he was going to leave the band. I don't know for how long, indefinitely or whatever. Other than that, I don't know."

As TMZ first reported, the band is forced to perform a "make-good show" in the Aloha State after losing a class action lawsuit -- which was filed after they canceled a show there in 2007.

The show is supposed to be "up to par" with their other concerts -- but according to the band's Sweeney Todd look-alike guitarist yesterday in D.C., there's one reason they might "play like s**t."

UPDATE: Brandee Faria, lead council for the class action lawsuit against Aerosmith, tells TMZ, "In response to the clip, I have no doubt that that Aerosmith is going to perform a spectacular show for their Hawaii fans. As an aside, if Mr. Perry wants to play poorly in a separate concert for me, he is welcome to do so and I'm sure I'll enjoy it nonetheless. I am the managing member of my firm, not an employee, so I'm not paid by the hour and consequently, never 'on the clock.'"

Steven Tyler and his bum shoulder will be gyrating on stage with the rest of Aerosmith next month in Hawaii -- and according to a court order, he's required not to suck at it.

Aerosmith will be performing concerts on October 18 and 20 in the Aloha State after losing a class action lawsuit back in July -- which was filed after the band canceled a 2007 show in Maui.

According to a clause in the settlement agreement, the gigs have to be the same "quality, type and duration" as a regular kick-ass Aerosmith concert -- which includes all aspects of the show, down to the "stage, lighting and sound quality."

Normally this wouldn't be a problem -- but the band was forced to cancel the rest of their 2009 tour in August after Tyler fell off stage at a concert and broke his shoulder ... so he isn't exactly in tip top shape.

Brandee Faria, the lead council for the suit, tells us, "They know they can't come out and do a 30-minute gig ... because I'll be there watching."

The video was shot yesterday in Pembroke, Mass.

Fear not Aerosmith fans, the 'Demon of Screamin' is alive and kickin' -- at least according to Steven Tyler's daugher.

Tyler's daughter Mia just gave TMZ one of the greatest statements we've ever received from anyone -- describing Steven's condition after that nasty fall he took on stage the other night:

"THE DEMON OF SCREAMIN IS NOT DEAD.

Yes it's true my dad walked the wrong way and landed on his head. He broke his left shoulder and had to get a few stitches on his noggin.

He is now at home resting and will be back on his feet just as soon as he can to rock the world once more."

Tyler injured his head, neck and shoulder from the spill -- and although he couldn't ruuuun away, ruuuun away from the pain ... he was able to make it to the hospital by helicopter.

UPDATE: Joe Perry's wife Twittered that Steven broke his shoulder and had to get stitches in his head and back.

61-year-old Aerosmith frontman Steven Tyler tried to entertain crowds with a crazy, spinning chicken dance last night in South Dakota -- and ended up flying off the stage.

He was airlifted to a nearby hospital after the fall -- he suffered minor head, neck and shoulder injuries.

Falling in love is so hard on the knees -- but falling on stage, that's hard for your head, shoulder and neck.

Aerosmith frontman Steven Tyler was airlifted to the hospital last night after falling from a stage in South Dakota midway through a concert.

The whole thing went down after the soundsystem failed during "Love in an Elevator" ... and Tyler began to dance to keep the crowd entertained.

It's unclear how serious his injuries were, but Tyler was reportedly still livin' it up after going down -- joking with the physician in the helicopter.

Josh was amused.

It's nice to see a band own up to selling out... even if it takes two years and a class action lawsuit filed by your own fans before you do it.

Aerosmith has announced plans to play a free concert for 8,300 fans in Maui -- but this is no handout -- because these people were the ones burned after the band canceled a 2007 show (sorry, no refunds) in order to play for some high-paying corporate big wigs... aka the "man."

The angered fans had tried to sue the band for lost costs, but it looks like all will be forgiven if the concert, which will take place in the fall after Aerosmith's North American tour, actually happens this time.

You know, assuming some insurance company doesn't want the band to play at a corporate luncheon or something.

In June, Guitar Hero: Aerosmith turned out to be the band's biggest hit yet -- in its first week of sales, the interactive game generated far more revenue than any Aerosmith album ... ever! To give you an idea, the band's latest studio release, "Honkin' on Bobo," had roughly $2 million in sales its first week; Guitar Hero: Aerosmith grossed roughly $25 million, according to RockGamer.

Who knew playing a glorified keytar would turn out to be so popular?

Aerosmith frontman Steven Tyler, 60, has checked himself into Las Encinas Hospital drug rehabilitation clinic -- the place Dr. Drew practices -- in Pasadena, Calif.

It's the same facility where the reality show "Celebrity Rehab" was filmed. Tyler is getting treatment for substance abuse.

Tyler's reps had no comment.

TMZ has learned that Kelly -- and all winners from seasons past, except Fantasia -- will be back performing on the "American Idol" stage for tonight's finale.

Clarkson, Ruben Studdard, Carrie Underwood and Taylor Hicks are headed to the Kodak Theater, but Fantasia Barrino won't be, since she is headlining Oprah Winfrey's production of "The Color Purple" on Broadway.

Sources tell TMZ Gladys Knight will perform "Midnight Train to Georgia" with the top six female finalists, while Smokey Robinson will join the top six male finalists for a rendition of "Ooh Baby Baby." Most recently booted finalist Melinda Doolittle will sing with brother and sister gospel duo BeBe and CeCe Winans, while the hairiffic Sanjaya duets with Aerosmith's Joe Perry to the Kinks' "You Really Got Me." It's sure to be an unbeweavable night!

Beat-boxing finalist Blake Lewis will show off his mad skillz against rapper Doug E. Fresh, and then duet with fellow finalist and probable winner, Jordin Sparks, to the Beatles' "I Saw Her Standing There." Since producers were able to finally get clearance to use Beatles music, a medley of Fab Four hits will be performed as well.

Luckily, we're told no one is expected to be exhumed a la Elvis on tonight's finale!

UPDATE: A well-placed source tells TMZ that anti-establishment rockers Green Day sold out and will be on the "American Idiot" "Idol" finale too!

Tyler was back at it again on the beaches of Maui this weekend. The rough ocean waves nearly pulled down the rocker's teeny bikini, but luckily for him -- and you, and us, and everyone -- he was able to pull them up before any real damage was done. Disaster averted ... mostly.
