Melissa Rivers is used to the awards show circuit, but now that dates porn king Steven Hirsch ... those awards show have a more XXX feel to them.

Rivers and Hirsch hit up the AVN Awards (pretty much the Oscars of porn) in Las Vegas last night. The couple happened to run into Joe Francis in the lobby of the Hard Rock Hotel, where the show was being held.

It's not every day that Tim Tebow agrees to hang out with a bunch of chicks who can put their legs behind their back ... but hey, Vegas is a special place.

The Denver Broncos QB went behind the scenes at Cirque du Soleil's "O" this week ... posing for pictures with some of the incredible flexible performers after taking in a show at the Bellagio.

As we previously reported, Tim was only in town for a few hours for a Nike photoshoot ... and stayed away from all of the usual Vegas temptations -- gambling, partying, buffets.

What happens in Vegas ... was pretty tame for Tim Tebow yesterday.

The Denver Broncos quarterback was spotted strolling through the Bellagio hotel last night along with his brother and a friend ... after catching a performance of the Cirque du Soleil show, "O."

We spoke to Tebow's rep ... who told us Tim was in town for a Nike photo shoot ... and was only in Vegas for the day.

We're told Tebow didn't gamble, didn't party, and definitely didn't attend the big AVN porn convention that happens to be going on down the street.

We asked how Tebow's ribs and lungs were feeling after the beating he took at the hands of the New England Patriots last weekend -- and his rep told us, "He's doing good ... taking his time to relax and rehab. He's been rehabbing non-stop."

We asked how Tebow would be spending his first free weekend in months ... and the rep told us, "He's looking forward to going to church."

Talk about having a death wish -- TMZ has learned, some dumbass broke into Mike Tyson's Vegas hotel room this weekend while the ex-boxing champ was sleeping ... but lucky for the intruder, dude escaped before Tyson could break his face in.

Sources tell TMZ, Mike was staying at The Cosmopolitan of Las Vegas Saturday night -- where he and his fam crashed after attending Stevie Wonder's New Year's Eve concert.

We're told Tyson was sleeping like a baby ... when all of a sudden, he awoke to rustling sounds and saw a flashlight. But by the time Iron Mike realized what was happening, the intruder had already run out of the room.

According to sources, security at the hotel was called and they are currently investigating the situation. Nothing was reported stolen from the room.

A rep for the hotel tells TMZ, "We have received a report of an incident that is currently under investigation. As always, guest safety is of the utmost importance."

Sources at the scene tell us ... Sofia and a girlfriend rushed over to the woman to help. We're told Sofia's friend had medical training and was seen checking the woman's pulse.

Both Sofia and her friend tried to keep the woman calm ... and waited by her side until security personnel and paramedics arrived to the scene. We're told the woman was eventually transported to a nearby hospital.

Kim Kardashian seems to be getting over her failed, very short marriage ... at least for an evening. She closed out 2011 by hosting a New Year's Eve party at TAO nightclub in Las Vegas last night.

There are reports that Kim, who arrived in Vegas via private jet, raked in $60,000 for the gig.

Kim's mom Kris was front and center ... and Mark Ballas was there in case she decided to break out and dance. Thankfully, she didn't.

Wonder if there are any auld acquaintances that Kim would rather be forgot and never brought to mind?

Vanessa Bryant is single and ready to mingle -- and TMZ has learned she'll be spending her New Year's Eve at a VIP table in one of the hottest clubs in Las Vegas.

According to our sources, Vanessa has reservations at Surrender, which is located inside the Encore hotel. It's the same hotel Paris Hilton was spotted at earlier this week.

Paris Hilton's war with Vegas titan Steve Wynn has apparently come to an end ... because she partied her face off at one of his nightclubs last night ... 15 months after she was banned from the property.

TMZ has obtained photos of Hilton getting down and dirty inside Surrender nightclub at Wynn's ultra-swanky Encore hotel in Vegas last night.

Paris had been blackballed from all things Wynn back in August 2010 -- after she was arrested for cocaine possession as she arrived to The Wynn hotel.

Paris has since completed her legal obligations -- now, it seems she's made good with Wynn, too.

Sources close to the couple tell TMZ ... the intimate event will take place at the Planet Hollywood Resort and Casino BEFORE Jason Trawick's big celebratory dinner.

We're told the owner of the PH -- Robert Earl -- will personally attend the event ... and plans to make a toast to the happy couple.

Britney Spears is getting engaged to boyfriend Jason Trawick, TMZ has learned.

Multiple sources who are definitely in the know say Jason plans to pop the question tonight ... in Las Vegas.

We're told Britney knows they're getting engaged, so it's not going to be a big surprise.

Sources say Britney's conservators have given their stamp of approval. The matter will go before the judge in the conservatorship case but it's virtually certain Brit will get the judge's sign off.

And we're told ... Jason did it the old fashioned way ... by asking Britney's dad, Jamie Spears, for permission to marry his daughter.

And they're also doing it the new-fashioned way ... we've learned there WILL be a prenup.

We're told Rich got into a verbal argument with a couple of passengers BEFORE boarding the plane ... and continued to display drunken behavior once he was allowed inside the main cabin.

A rep for Southwest confirmed a passenger was kicked off the flight, but would not release the person's name.

The rep tells us, "Our crew assessed the situation and determined that the passenger was not fit for travel under governing federal aviation regulations."

Snoop was surrounded by an army of super-flexible lingerie-clad models at Gallery nightclub at the Planet Hollywood -- but don't worry, his wife was there too.

So there he was, partying in Vegas ... when Marc Anthony noticed two U.S. marines hanging out at the Venetian ... and decided he was going to show his appreciation, by treating them to most kick-ass night EVER.

TMZ has confirmed ... Anthony approached the two marines and personally invited them to hang with him at Tao nightclub Thursday night -- hours before Veteran's Day.

We're told Anthony treated the guys like rock stars -- ordering bottles of expensive booze at a private V.I.P. table and making sure everyone knew they were the guests of honor that night.
