Marc Anthony's new GF Chloe Green is the daughter of UK billionaire Sir Philip Green -- which is awesome for Chloe and Marc, but not so awesome to one fashion-obsessed shopper.

Not to worry ... one good sale, and she'll get over it.

Marc Anthony and his kids hit up Disneyland with his new girlfriend who is both hot and billionaire-adjacent.

The new GF is Chloe Green, daughter of UK billionaire Sir Philip Green, whose estimated net worth is $5 billion.

It's a good bet Sir Philip provides his daughter with an endless supply of loot. He reportedly dropped $6 million on his son's Bar Mitzvah -- a lot more impressive than a bunch of useless savings bonds.

In related news ... Casper Smart just got a big raise in his allowance.

Marc Anthony pulled a page from his ex Jennifer Lopez's post-breakup play book and frolicked on the beach with his much younger hot lover Shannon de Lima in Miami on Thursday.

The scrawny 44-year-old Latin crooner and his 24-year-old Venezuelan model girlfriend are definitely enjoying their moment in the sun.

Marc Anthony isn't just on good terms with his estranged wife Jennifer Lopez ... he's also on good terms with the guy who's bangin' her ... at least judging by this photo.

TMZ has obtained a photo of Casper Smart in a great, big bro hug with Marc at a private airport in NY yesterday.

We're told the kids -- Emme and Max -- have been hangin' with J.Lo and Casper during the most recent leg of Jenny's international tour ... and when they arrived back in the States on Monday, daddy was right there to greet them.

Sources tell us ... things seemed very friendly and the kids appeared happy to see their dad.

Jennifer Lopez desperately wants to bring her children on her upcoming world tour with Enrique Iglesias -- just one problem ... the kiddies are not allowed to cross California state lines.

When J.Lo and her soon-to-ex husband Marc Anthony filed for divorce -- the judge ordered both sides to keep Emme and Max within the confines of Cali unless they get permission from the court.

So J.Lo has filed documents ... explaining that both she AND Marc are about to embark on separate concert tours ... and they both want time with the kids while on the road.

In the docs, Lopez says she and Marc will be able to work out the scheduling.

A hearing is set for June 26. J.Lo's concert tour with Enrique is set to kick off in July.

Jennifer Lopez isn't the only one running around town with a hot piece of ass who's half her age ... Marc Anthony's got a hard-bodied 24-year-old of his own ... and last night, he trotted her out in a SKIN-TIGHT sausage-casing of a dress.

43-year-old Anthony has been dating Venezuelan model Shannon De Lima for several months ... and last night, the two strolled in to a private party together in Miami Beach.

With J.Lo still playing chaperone to her ripped boy-toy Casper Smart ... we gotta ask ...

Marc Anthony held out hope for a reconciliation with Jennifer Lopez, but decided to file for divorce when she told him ... she's madly in love with BF Casper Smart ... TMZ has learned.

TMZ broke the story ... Marc filed for divorce Monday -- nine months after the couple announced they were splitting.

But sources extremely close to Marc tell us, he didn't make the decision on his own -- he had a heart-to-heart with J.Lo a few weeks back to see if she really, truly wanted to end the marriage.

We're told he said he wanted to give the marriage another try, but Jennifer confessed ... she was deeply in love with Casper ... and wanted to pursue that relationship.

We're told Marc was blindsided ... he had not idea things were so serious -- and he was hurt.

So that's why Marc filed divorce papers this week.

Marc Anthony has finally filed for divorce from Jennifer Lopez ... TMZ has learned.

Marc cites "irreconcilable differences" as the reason for divorce.

In the papers, filed April 9 in L.A. County Superior Court, Marc is asking for joint legal and physical custody of the couple's twins, Emme and Max -- who are 4 years old.

Marc wants the judge to shut the door on Jennifer if she asks for spousal support.

Marc does not list a specific date of separation, but the couple announced their split back in July.

They married in 2004.   This will be Jennifer's 3rd divorce and the numero dos for Marc.
He wants each party to foot the bill for their own attorney's fees.

Marc Anthony and Jennifer Lopez possibly getting back together means only one thing -- J.Lo's boy toy Casper Smart better enjoy the Bentley and those sweet vacas while he can! Tick, tock ...

Jennifer Lopez and Marc Anthony have found the secret to getting along -- splitting up.

Sources very close to the former couple tell TMZ ... months before the breakup, there was virtual radio silence between the two. We're told when they did talk, it was loud and contentious ... often ending in tears on Jennifer's part.

But since the split, we're told their bond has materially strengthened. They are communicating and co-parenting well and not fighting at all.

We're told they're actually happy to do joint appearances for their new show, as well as charity work.

Sources say a number of people around them are saying there are signs of a possible reconciliation, although it is by no means certain.

Marc Anthony is making things permanent with his new 24-year-old hottie -- by branding himself with a tattoo of the Statue of Liberty ... a tribute to his GF and his new found "freedom."

Sources close to the singer tell TMZ ... Venezuelan model Shannon De Lima was with Marc when a spot-on replica of Lady Liberty was tatted inside his right wrist on New Year's Eve in Miami. Marc's 17-year-old daughter Ariana (above, right) was also front and center.

We're told "Statue of Liberty" is Marc's pet name for Shannon ... because she "freed" him from his past. While he was at it -- Marc and Ariana also got unspecified matching tats on their outer wrists.

Fun fact: A "Jennifer" tattoo used to be on Marc's right wrist. Let freedom ring.
