Cardi B Stefon Diggs

Stefon Diggs cut the cord and then Cardi B turned it into gold ... because Cardi took their newborn son's umbilical cord and got it transformed into a pendant.

The "Bodak Yellow" rapper enlisted Mommy Made Encapsulations to turn the umbilical cord into some heart-shaped, gold jewelry.

In the video shared online, Mommy Made Encapsulation takes folks through the transformative process ... the umbilical cord is shaped into a heart, dehydrated and then dipped in gold chrome.

11/17 5:17 PM -- Offset's rep tells TMZ ... "Any statements attributed to Offset circulating on social media are completely fabricated. Cardi responded to misinformation, and the situation escalated unnecessarily. Offset has remained supportive of Cardi and genuinely wishes her nothing but the best."

Cardi B has had enough of estranged husband Offset's alleged harassment ... she says his behavior is starting to make her fear for her life.

After filing for divorce from the Migos rapper and moving on with boyfriend, NFL star Stefon Diggs, Cardi claims Offset is still "obsessed" with her. And she's got a point ... Offset recently suggested that Cardi's kid with her new man could be considered his child according to Georgia law in tweets he's since deleted.

Cardi warned those who might laugh at the seemingly absurd drama, saying, "Y'all be thinking it's so funny and it's not ... It's all fun and games until it's too late."

Cardi B was spotted getting sweated out by Stefon Diggs in a workout vlog posted today ... because reports of them breaking up are bogus!!!

A source close to the couple tells TMZ she and Stefon are not officially broken up ... in spite of the "Bodak Yellow" rapper wiping her IG slate clean of their romantic union.

Cardi seemed to make an attempt to clarify the relationship was still on ... by reposting a clip from his vlog of the two working out together while vacationing in Europe last month.

Cardi B and Stefon Diggs may have run into a snag in their relationship 'cause Cardi has hit the ol' "delete" button on her boyfriend!

The rapper took to Instagram over the weekend and erased all of her photos with the New England Patriots wide receiver, which is never a good sign.

You may recall, just last month, the two went Instagram official weeks ago and the couple seemed to be in their honeymoon phase.

Cardi B is getting the royal treatment -- Stefon Diggs hooked his lady up with an entire castle for their vacation in France ... where they'll be able to eat, sleep and poop like King and Queen!!

The rapper shared a tour of the temporary digs on her Instagram Story ... and the place comes complete with a moat, dining hall, indoor pool and themed bathrooms!!

During the walkthrough, Cardi cracked a joke about the toilet -- which looks like an elevated hole with a lid (don't worry, there's actual plumbing) -- saying, "this is where we take the royal s***" before panning to the tub, which is "where I will wash my royal hiney."

Cardi B still has murderous thoughts of her estranged husband Offset ... but her new romance has opened up a new chapter for her soft-girl era!!!

An insomniac Cardi hopped into X Spaces early Tuesday morning to vent to her fans about how much trauma Offset caused her in their last few years and admit had she not left him, she'd be in jail -- for MURDER.

You can hear her fighting through tears ... Cardi says Offset cheated and lied so much, she'd wake up in fear over being looped into an embarrassing trending topic.

Cardi B and Stefon Diggs aren't letting rumors -- or estranged exes -- muffle their love for boats, judging from their sizzling getaway weekend!!!

On Sunday, Cardi and the NFL star created their own waves on a yacht in the middle of the ocean, and the "Bodak Yellow" rapper kicked up her red bottoms to smell the garden of red roses her new beau had gotten her!!!

Other gifts included giant teddy bears and bouquets of yellow, purple and white roses. Cardi also flashed her hand holding a designer lizard-skin handbag while chunked with tons of diamond-encrusted jewelry, although it's unclear if it was all from Diggs.

Stefon Diggs' weekend boat trip with Cardi B has made it to his boss' desk -- New England Patriots head coach Mike Vrabel was asked all about the video making rounds during media availability on Wednesday ... and he said the team is well aware of the matter.

The 31-year-old wide receiver raised eyebrows after a short clip was published all over the internet on Tuesday ... showing him chatting it up with three women in bikinis before opening a container to expose a mystery pink substance.

In the video, he appears to tell the women to not take all of it ... but instructs them to go have fun and come back to him.

Cardi B and Stefon Diggs looked cute and coupley while making their first official public appearance together amid dating rumors ... strolling up to Monday's Knicks vs. Celtics game at New York City's Madison Square Garden hand in hand.

They looked just as smitten inside the famous venue -- the "Wap" hitmaker at one point placed a hand on her rumored beau's thigh ... and was later photographed sweetly caressing his face.

In another pic, Stefon looked cool and confident with his arm wrapped around Cardi ... possibly confirming what fans have been speculating for months -- that she's all his.

Things are heating up between Cardi B and Stefon Diggs ... the pair was once again spotted together (this time in an NYC club), with the rapper giving the football star a sexy dance!

Offset, Cardi's ex-hubby, even weighed in on the budding rumored romance.

Fresh off signing a $69 million deal with the Patriots, Diggs hit up a Manhattan nightspot with the "WAP" rapper ... where she was seen giving him a seductive lap dance.

Cardi B continues to fuel romance rumors with Stefon Diggs ... 'cause the two painted Miami "Bodak Yellow" late Friday night.

TMZ has obtained videos and photos showing the rapper and the NFL wide receiver arriving to a Miami hotel in the wee hours of Saturday morning ... with Cardi dressed up all sexy in a revealing dress.

Check it out ... Cardi's dress is clinging to her frame -- and, when she bends forward, her entire bust is on display. Diggs dressed in all-red for the occasion, looking comfortable in a jacket and baseball cap.
