For the first time since the engagement news broke, Brad Pitt and Angelina Jolie were spotted together ... seen here being driven to a private plane at an airport on the Galapagos Islands. 

The couple has reportedly been there for most of this week on a post-engagement trip with their entire brood.  

Though the couple has finally decided to tie the knot after years of dating, there has been no word yet on when the wedding of the millennium might go down.

Angelina Jolie pulled a very special "Jolie" earlier today -- showing some leg on Hollywood Blvd ... while brandishing her fat new engagement ring.

The 36-year-old actress is serious wife material.

A gay rights group in California fully supports Brad Pitt and Angelina Jolie's decision to tie the knot ... even though Brangelia always swore they wouldn't get hitched until everyone had the right to marry.

As recently as last September, Brad told Ellen DeGeneres, "I’ve said that we would not be getting married until everyone in this country had the right to get married." 

But Rebekah Orr, Communications Director for Equality California, says the group is totally behind the Brangelina marriage, even if the right to marry is still not enjoyed by everyone.

She tells us, "Marriage is something that says ‘we're a family’ in a way that nothing else can ... No one has to deny that for themselves or their family to prove they are an ally and supporter of equality."

Brad and Angelina finally announced yesterday they were getting married, even though they've been together for seven years and have six kids. 

After 6 children and 7 years as an unmarried couple, Brad Pitt and Angelina Jolie are finally engaged -- this according to Brad's rep.

Brad's manager Cynthia Pett-Dante released a statement confirming the engagement, but says there's no wedding date yet -- as of now, the engagement is simply a "promise for the future."

Angelina was photographed on Wednesday wearing what appears to be her engagement ring. Click here for the photo.

Pitt and Jolie met on the set of "Mr. & Mrs. Smith" back in 2005. They have three biological children (the twins Vivienne and Knox, and daughter Shiloh) and three adopted children (Maddox, Pax, and Zahara).

Brad and Angelina had previously stated they would NOT get married until gay people could get married too -- but admitted their children were pressuring them to tie the knot.

This will be Brad's second marriage and Angelina's third. Angelina was previously married to actors Jonny Lee Miller and Billy Bob Thornton. Brad was previously married to Jennifer Aniston.

Jennifer Aniston is still unmarried. 

Brad Pitt's "Moneyball" was 133 minutes of unbearable, brain-melting MISERY ... this according to Mickey Rourke.

Rourke was leaving the gym in L.A. yesterday when he joked about using the movie as a torture device ... "I'm gonna tie you to a chair and make you watch 'Moneyball' all f*cking night."

For the record, Rourke and Brad Pitt don't seem to have a beef ... in fact, there are all sorts of pics of them smiling together over the years. Guess he really just HATED the movie.

So, we gotta ask ...

TMZ has obtained photographic evidence that food, or rather a bag containing food, touched the hands of Angelina Jolie today in Los Angeles.

It is unclear whether or not this constitutes "eating."

According to our sources, she would have to consume the food inside the bag for it to constitute "a meal."

Jolie was the passenger in a car driven by Brad Pitt as they made their way through a McDonald's drive-thru.

Calls to a rep for Angelina's right leg were not returned.

Like the king and queen of the Hollywood prom, Brad Pitt and Angelina Jolie -- and her legs -- were among the last to arrive to the Academy Awards on Sunday.

We are not worthy.

Newt Gingrich is adamant ... Brad Pitt should play HIM if Hollywood ever made a movie about his life ... and no, that's not a typo.

The Republican candidate phoned in to the Rich Stevens Radio Show today ... when he was asked, "If Hollywood was going to do a movie about your life, who would you like to see play the lead role?"

Newt replied, "Oh, in my fantasy life? Brad Pitt ... why not?!

Stevens quipped, "Is it because you guys look alike?"

Newt fired right back. "No, I don’t look like him at all. He's thinner, he's better looking, he's younger. But you asked me if I had anyone who could play me in a movie ... why not go for Brad Pitt???"

We called Pitt's people for comment -- so far, no word back.

Angelina Jolie, Brad Pitt, and all of their various children hit up "Michael Jackson: The Immortal World Tour" in Las Vegas last night.

Perhaps the tix were a birthday gift ... Brad turns 48 today.

Brad Pitt and Angelina Jolie ... ACTUALLY TALKED TO US!!!

It all went down after the two had dinner at Boulevard3 in L.A. -- when BOTH superstars approached the photogs and chit-chatted it up.

Brad finally revealed why he refuses to sign autographs in blue ink ... and Angie pulled off one HUGE favor for one super-lucky fan. 

Great up-close-and-personal footage of two of the biggest stars in the world -- check it out.

Hungarian police raided the set of Brad Pitt's new movie today -- confiscating a massive stash of high-powered guns ... including AK-47s and sniper rifles ... filled with live ammo.

According to Hungarian authorities, the guns -- which were to be used as props in Brad's new zombie flick "World War Z" -- hadn't been properly disabled, and some even contained live rounds.

Authorities seized 85 weapons in total from a warehouse in Budapest -- and called the entire situation "a disaster waiting to happen." Brad was not present during the raid.

A publicist for the film claims ... "We are working with the authorities to resolve the matter and have no further comment at this time."

TMZ placed calls to several people in Pitt's camp -- including his production company and his manager -- so far, no word back.
