Unless your New Year's Eve party featured Steven Tyler and Alice Cooper on the same stage performing the classic song "Come Together" ... you were not at the coolest NYE around. 

Tyler and Cooper performed at Mala Restaurant in Wailea, Hawaii ... and Cooper can be seen reading the lyrics to keep up with Tyler, who covered the classic Beatles track with Aerosmith back in 1978. Watch closely for a Weird Al cameo as well.

Tyler also performed "Sweet Emotion" and "Walk This Way."

What a way to ring in 2012.

Kim Kardashian is all set to return to the "Pussycat Dolls" ... only this time, she'll be running things BEHIND THE SCENES -- as the executive producer of a new PCD reality show ... TMZ has learned.

Kim signed a TV deal with "American Idol" honcho Nigel Lythgoe -- to be the E.P. for an upcoming reality show about the "Pussycat Dolls empire" ... that will feature the launch of a "new" PCD group.

One source tells us the newbies are "10 times better than the original group."

We're told Kim has a good relationship with PCD founder Robin Antin -- plus Kim really enjoyed performing with the group in Vegas a few years back.

Kim is telling friends she's "super excited" to work with Nigel because "he's the best in the business."

Here's hard rocker Alice Cooper in NYC last night (top) -- and lip-synch wonder Britney Spears back when she could give a great live performance in 2001 (bottom).


One was just inducted into the Rock and Roll Hall of Fame.

We're just sayin'.

Sylvester Stallone's SICK 1955 custom-built truck that he drove in "The Expendables" just went to the highest bidder at an AWESOME celebrity car auction in Arizona this weekend for $132k ... TMZ has learned.



According to the Barrett-Jackson auction company, the truck -- which was custom built by the guys at "West Coast Customs" -- had all sorts of badass features including a new Ford 347cid Edelbrock engine and awesome race seats.

But the craziest part about the truck -- it comes with "hidden compartments to hold movie weapons."

Stallone's ride wasn't the only AMAZING celebrity automobile on the auction block -- Evel Knievel's famous truck ... Alice Cooper's custom Camaro ... and even a car used by Elvis ... they all sold for big numbers.



Check out the gallery to see how much each ride pulled in.

Jurassic rock icon Alice Cooper, 62, and "Expendables" star Sylvester Stallone, 64, giggled together at the same event in London on Monday.



Question is ...

The remains of goth rockers Marilyn Manson, 41, and Alice Cooper, 62, were exhumed at the same event in L.A. on Thursday.



Question is ...

After over 30 years of performing, it's nice to see 61-year-old Alice Cooper still gets really excited to be on stage.


Either that, or rigor mortis has set in.

Plainclothes goth rocker Alice Cooper was busted for putting the pedal to the metal in Arizona a few months back -- after one of those pesky photo enforcement cameras caught him going 14 MPH over the speed limit.



Lacking his usual black mascara and trusty boa constrictor accessory, Cooper was snapped doing 59 in a 45 at an intersection in Maricopa County on May 23.

Lucky for Cooper, he didn't have to go to traffic school over the offense -- he just paid a $175 fine.

On Tuesday in Australia, Jurassic rocker Alice Cooper started his day on the golf course (left) -- and ended it on stage, looking like a corpse (right).


The 61-year-old has credited golf with helping him overcome his alcohol addiction.

Unfortunately, Alice still hasn't found a cure for his dependence on age-inappropriate leather and embalming makeup.

Here's 61-year-old rocker Alice Cooper (left) at a concert in Australia over the weekend -- and Leatherface (right) in the 1974 horror classic "The Texas Chain Saw Massacre."


One of them wears a mask of dead flesh.

We're just sayin'.

In the '70s, Alice Cooper (aka Vincent Furnier) became famous for songs likes "School's Out" and his creepy heavy metal theatrics. Guess what he looks like now!
