Mark Zuckerberg, Priscilla Rome During Honeymoon

Mark Zuckerberg and Priscilla Chan blended with the crowd during their honeymoon in Rome -- as best as a gazillionaire can blend.

It looks like they didn't attract much attention -- in fact, they seem to go unnoticed by most people in the crowded restaurant in the middle of the famed city.

Italy is fitting, because Mark said "arrivederci" to around 3 billion bucks this week after his Facebook stock took a nosedive.

Mark Zuckerberg's Wife The SIMPLE Ruby Wedding Ring

If Mark Zuckerberg's new wife was expecting a MASSIVE diamond on her wedding ring ... she was SORELY disappointed.

Just days after the surprise wedding of the century, Priscilla Chan-Zuckerberg took her brand new ruby rock on the road ... flashing her piece during a lunch date with a friend in Palo Alto, CA yesterday.

According to reports, the $20 BILLION Facebook honcho -- who has a reputation for not caring about excessive displays of wealth -- designed the ring himself.

It's unclear how much the ring cost ... hopefully not much ... 'cause his Facebook stock has been sinking like Natalie Wood ever since it debuted on Friday.

So, we gotta ask ...

Bobby Brown and Fiancée Say Aloha to Our Wedding

Bobby Brown is managing to kill two giant birds with one stone ... a concert with his band and his long-awaited wedding -- all in one weekend trip to Hawaii.

Sources tell TMZ ... Brown and his fiancée -- Alicia Etheridge -- have finally set a wedding date after 2 years of engagement bliss ... and it's the same weekend Brown's band New Edition will be performing in Honolulu.

We're told the nuptials will take place on the weekend of June 15th ... Brown will be flying out some of his family and friends to the island, to witness the ceremony he has dubbed his "big day."

The duo has been engaged since May 2010 and have one child together.

Bobby was previously married to Whitney Houston who passed away in February.

FYI -- It's also Father's Day weekend ... so 3 birds and one volcanic sized stone.

'Biggest Loser' Wedding NO BOOZE ALLOWED

"Biggest Loser" contestant Joe Messina's recent nuptials violated the one cardinal rule of weddings everywhere -- GET EVERYONE WASTED -- because booze was NOT allowed at the party.

TMZ broke the story ... the former Season 13 contestant tied the knot recently in Michigan -- and 12 other current and former contestants attended -- but the wedding party lacked a key ingredient .... alcohol.

Sources tell us ... the groom and his "Loser" guests are serious as a heart attack when it comes to their new healthy lifestyle -- so they axed all forms of alcohol from the menu (alcoholic drinks contain a lot of calories). Thankfully, we're told the crowd -- which was pretty religious -- didn't drink much anyway.

But Joe's reign of terror didn't end there -- we're told he also subbed a real wedding cake for low-fat pumpkin cake pops ... and served only food from the "Biggest Loser Cookbook" ... such as:

-- Grilled Chicken with Mango, Thai Quinoa Salad
-- Tossed Salad
-- Fresh Fruit Salad
-- Asian Chopped Salad
-- Salad Salad

And just when you thought it couldn't get any worse ... we're told the guests actually WORKED OUT before the ceremony.

No one was injured.

Jennifer Aniston Scouting Trip to Crete for Wedding

Jennifer Aniston and boyfriend Justin Theroux are planning a wedding thousands of miles away from Hollywood ... TMZ has learned.

Sources connected with the Elounda Beach Hotel in Crete (where Aniston's dad was born, located about 230 miles south of Greece) tell TMZ ... Aniston was there recently, scoping the place out. Our sources say Aniston mentioned a July wedding.

The hotel website boasts a wedding package that includes:

-- A dedicated consultant
-- Legal, License Paperwork Requirements
-- Civil or Religious Ceremony outside of the Hotel’s Church
-- Bridal Bouquet, Groom's Boutonniere, decoration of the club car
-- Bottle of champagne & Greek Wedding Sweets after the ceremony for the bride & groom

You get all that, plus a series of other complimentary services, for about $2,300.

Aniston made that for roughly 2 seconds of work on "Friends."

BTW, one of the hotel big wigs says Aniston hasn't settled on his hotel for the nuptials ... as he put it, "She has connections on the other side of the island as well."

'American Gypsy Wedding' The Craziest Boob-Exposing Eye-Gouging Catfight Of All Time

Every reality show on the planet should give up NOW -- because the girls on TLC's "My Big Fat American Gypsy Wedding" just set the record for the wildest, most ruthless catfight of all time ... and it was all caught on tape.

The fight went down last November at a "gypsy" wedding in West Virginia -- the smaller girl (Mellie) hails from the groom's side and the bigger girl (Diamond) was the maid of honor.

Sources tell TMZ, neither side of the family exactly approved of the union -- but Mellie took it one step further after the ceremony ... running her mouth about how the bride and groom don't belong together.

Diamond caught wind of it ... and FLIPPED -- shoving Mellie to the ground outside the church.

At that point, both girls unleashed fist-flying hell -- beating the living crap out of each other and pulling at each other's clothes until they were naked ... literally.

If you watch one clip on the website today ... make it this one. Trust.

Brangelina Engagement: Gay Marriage Group Gives Their Blessing

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.

Brad Pitt & Angelina Jolie ENGAGED!!!

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.

'Californication' Hottie I'm Marrying a Preacher Man!

Lingerie-wearing "Californication" actress Meagan Good has decided to take on a more heavenly role -- TMZ has learned ... she's now engaged to her preacher BF.

Meagan's rep tells TMZ, 30-year-old Good recently got engaged to DeVon Franklin -- an exec at Sony Pictures Entertainment who leads a double life as a 7th Day Adventist preacher.

A little rundown on your typical 7th Day Adventist -- he takes the Bible pretty literally, practices Sabbath on Saturday, doesn’t eat pork and frowns upon alcohol ... not that there's anything wrong with that.

According to Meagan's rep, the preacher proposed last month in L.A, but the couple has known each other for years. They began dating just after production wrapped on "Jumping the Broom" ... which Meagan starred in, and DeVon produced.

No date yet for the wedding ... but an open bar is probably out.
