TMZ has obtained photos of
Dave Navarro and
Brooke Mueller Wednesday -- the night of their infamous Apsen make-out session -- and also unearthed semi-scientific information that could be dangerous to both of them.

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.
Stay safe.
Dave Navarro helped
Brooke Mueller get over the pain of her impending divorce from
Charlie Sheen last night in Aspen -- with a crazy public make-out session!

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.
Happy New Year!
Reassembled rock chick
Courtney Love and former Red Hot Chili Pepper
Dave Navarro put on quite the performance in Hollywood last night.

After taking the stage at a Camp Freddy show at Hollywood & Highland, Court and Dave proceeded to makeout.
A duet made in grunge, er, nirvana.

Julianna Margulies on the TV series "
The Good Wife" (

At least one of them could use a little lipstick.
We're just sayin'.
Dave Navarro and
Backstreet Boy A.J. McLean got shady at the same event in L.A. on Thursday.

Question is ....
It's a nasty, dirty habit -- but as Dave Navarro knows, once you're addicted, it's hard to function without firing through at least a couple a day. Not cigerettes -- hot chicks. Dave just can't seem to help himself.
Dave Navarro is a dirty man -- but he won't screw around with your girlfriend.

Ex-Mr. Carmen Electra gave Miss Malibu a special tour of his trailer this weekend -- but when the Dave found out the beauty queen had a boyfriend, she claims he kicked her ass back on to the curb.
Gotta respect a rockstar with standards.
It's not every day that someone can just walk up to Tom Cruise in the streets for a photo-op -- but it's always awkward when it takes more than one shot to get it right.
Dave Navarro told us about the movie he rented regarding man/horse relations, two grown men fought over the chance to take a pic with Mini-Me and Jessica Simpson's parents showed that they don't have high hopes for her country career.
57% of you thought Dave Navarro was mackin' on a weird-ass blue
dude in Miami -- but was it really? Our photog went straight to Dave for the answer to this gender bender.
Hope you enjoy the theme song -- and
check local listings for TMZ TV.

Dave Navarro has made out with women, men and even Tommy Lee, but the gender and species of his latest suck fest is unclear.
While backstage at his Miami concert, the 40-year-old tatted up muscled musician swapped spit with a "dancer" of unknown origin.
TMZ finally has
a good question for Dave: What were you kissing?!
Dave Navarro trashed our questions yesterday -- and, you know what, he was kinda right.
Yeah ... Heather Graham wasn't too happy with that plastic surgery question yesterday either.
