Hook Ups

TMZ spoke to someone who made it into Sheen's penthouse suite at The Palms Hotel on Sunday ... who tells us, "It looked like porn star auditions ... the girls were all over him and he just sat back and took it all in."

As we previously reported, Sheen had been hanging out with porn queen Bree Olson (blonde)... who invited Bombshell McGee (tatted, left) and BM's friend Lindsay Sinai (tatted, right), to come party in the suite. Apparently, they weren't the only ladies who got the invite ...

Our source tells us Charlie "loved the attention" ... and seemed like he was "in his environment."

The "Two and a Half Men" star caught a flight home the next day -- despite an ear infection -- and returned to work this week.

We're told Bombshell and Bree befriended each other hours before their on-stage makeout session for Pauly Shore's comedy show at The Palms on Sunday.

After the kiss, we're told Bree invited Bombshell to come back to Charlie Sheen's penthouse later that night ... and lo and behold, she did.

Around 2 AM, we're told Bombshell and a friend rolled over to Charlie's room -- only to discover a "trainwreck inside" ... consisting of Charlie, booze, and a whole lotta women.

The girl-on-girl action went down at The Palms Hotel on Sunday ... where the next day, Sheen was spotted taking a shot of Grey Goose at a hotel bar.

We're told the vodka session was the tail end of an epic "bender" -- and Bree, along with two mystery porn stars, was with Charlie for some of the action.

But, as TMZ previously reported, Sheen's people are very concerned about the actor's health -- and members of his inner circle have been urging him to check into a rehab program. We're told Charlie doesn't think he has a problem.

A moving truck showed up Tuesday ... we're told to take Jordan Bratman's stuff away, and none too soon. We're told current BF Matt Rutler moved in weeks ago.

As one source connected with the threesome put it, "Thank God Jordan is moving out. It was getting really awkward, but Christina was letting Jordan stay for the sake of Max."

The couple has reportedly been dating on the down low for the past couple of weeks -- even spending some QT together on Martha's Vineyard recently.

Nothing like some PDAs to up your teen super-couple status.

As we first reported, the pair swapped spit during a smoke break while out to dinner at Aspen's Nobu Wednesday evening.

But here's the thing ... they say when you kiss someone, you're kissing everyone they have ever kissed. So considering the dating history of this pair -- Carmen Electra and Charlie Sheen, respectively -- these two have now made out with pretty much everyone on Earth.

Our Aspen spies spotted the two downstairs at Nobu, at around 8:15 PM.

We're told Jane's Addiction band members and Brooke were at the table. Dave went outside to smoke and Brooke followed ... once outside they began to "full on make out," as Dave had his hand on her chest.

They came back inside, got their stuff and left together.

Eddie popped the question a few days ago -- and if you're keeping score ... the ring is a 5-carat oval diamond set in rose gold fleur-de-lis connected to the band.

Back in 2008, the Disney starlet vowed to abstain from sex until marriage and donned a promise ring to prove it. But last weekend Selena was spotted going into Justin's tour bus without the chastity symbol around her pure little finger.

TMZ has learned ... both Rachel and Tiger Woods have been invited to Donald's annual New Year's Eve bash at his Mar-a-Lago mega-estate in Florida.

As for Tiger, Donald tells TMZ, "I did invite him. I'm the only guy who has tried to defend him."

Rachel, as usual, is a little more complicated. She has a "blind date" with a guy in the New York fashion industry whom Donald invited, and Rachel is coming as the plus one.

Donald tells us, "She's absolutely welcome."

During a kiss and tell session on the "Woody & The Wake-Up Call" show today on WCOL -- Gene says he took "Polaroid photos of the ladies who graced the bed in my room" during his 37 years of touring with KISS.

Gene then copped to having "right under 5,000" Polaroid snapshots of his conquests -- with each woman holding the key to the hotel room where Gene conducted the coitus.
