Meredith Marks showed Mary Cosby a little love during a DJ set overseas ... with a touching tribute to her BFF and reality TV costar following her son Robert Cosby Jr.'s death.

The 'Real Housewives of Salt Lake City' star was spinning tunes at the Mighty Hoopla music festival in the United Kingdom when she cued up the choir version of Madonna's "Like a Prayer" while a 'RHOSLC' scene of Mary speaking at church played behind her.

As we reported ... Mary's son Robert Jr. died in February at just 23 years old. His cause of death is still unclear, but we know cops found him while responding to a possible overdose.

Latto says her new song is about Cardi B calling her a "p***y ass" ... but she says her response isn't exactly a diss ... and it sounds like she might be down to mend fences.

Big Mama went on "The Breakfast Club" Thursday and addressed the drama head-on, telling the show's hosts those lyrics in her new song "Gimme Dat" are, in fact, about Cardi.

The rapper says she was caught off-guard when she caught a stray during Cardi's leaked rant about Ice Spice ... because she had just rushed out her verse for the "ErrTime" remix so it would count toward Cardi's first-week album sales.

Latto recalled how a couple days after she tried to help out Cardi, a peer she thought was a friend was all over the internet calling her a "p****."

She was pregnant at the time, and Latto says she put her feelings on wax while her hormones were raging.

As we reported ... on "Gimme Dat," Latto raps ... "Bitch said what? Let’s clock it / Really got a Hermes store in my closet / Talkin’ ‘bout buyin’ big mama a bag like my n**** ain’t already bought it."

Cardi apologized online ... but Latto says they have each other's numbers and have texted before, so she wasn't feeling the way Cardi handled things.

While Latto says she hasn't spoken to Cardi since the “ErrTime” remix was released in September, she says she's open to hashing things out.

Latto says folks think it's a diss because they're just hearing the song now ... but she says she was just rapping about what was going on in her life at the time ... and while it's not a textbook diss track, Cardi still left a bad taste in her mouth.

Alix Earle is adding another credit to her growing résumé -- 'cause TMZ has learned she's been tapped for Benson Boone's latest music video.

Sources with direct knowledge tell TMZ ... Benson personally asked Alix to appear in the video for his new song, "The Time of My Life," and she was all in.

We're told cameras are set to roll very soon, and Alix is excited to be part of the project.

Legendary bassist John B. Williams -- best known for playing on "The Tonight Show Starring Johnny Carson" -- is on hospice being cared for by 'round-the-clock nurses, TMZ has learned.

His wife, Jessica Williams, tells TMZ ... he recently suffered a fall and subsequently underwent brain surgery as a result of his injuries. Jessica, an accomplished musican herself, says John had dementia prior to the fall, but the fall greatly accelerated its progression.

At this point, John is unable to walk and can't talk, and his health is on the decline. We're told one if his last conversations was with his daughter.

Want to start your day on a high note? We've got just the thing -- Jason Momoa shredding a guitar shirtless in the California desert!

The "Aquaman" star ditched his top while joining his band, ÖOF TATATÁ, for a sound check at The Red Dog in Pioneertown ... and if the abs didn't grab your attention, his guitar skills probably did.

Jason was spotted entertaining a crowd that gathered to catch the rehearsal ahead of the group's limited West Coast run, turning a simple sound check into its own mini show.

The Black Crowes are set to hit the stage tonight, days after they got into it with fans over a chant about the red, white and blue ... and the backlash hasn’t messed with ticket sales, TMZ has learned. 

A rep for the SJC Cultural Events, Inc., which owns the St. Augustine Amphitheatre where the group is performing Tuesday night, told TMZ this afternoon ... "At this point, we have not had any request for refunds."

At Sunday's show in Tampa, fans who attended the show claimed The Black Crowes’ singer Chris Robinson went off after the crowd started a patriotic chant … after seeing the band's Black Crowe character on the big screen dressed as Uncle Sam. 

Damon Dash is firing back at Jay-Z after his former Roc-A-Fella partner dissed him at the Roots Picnic ... and Damon isn't feeling the bars ... or the hair.

Speaking with "The Art of Dialogue," Damon dismissed the freestyle as recycled material, claiming Jay was leaning on old jokes and wasn't delivering the sharp lyricism he once brought to the table.

Take a listen ... Damon didn't stop at the lyrics.

Klay Thompson apparently did Megan Thee Stallion so dirty it sounds like we're getting a banger out of this celebrity breakup.

The rapper teased a new song Tuesday, and it certainly looks like she's about to show her NBA baller ex how badly he fumbled.

In a snippet from a new song, Meg is living it up on a yacht rocking a skimpy bikini, twerking, and partying with her girls as she raps, "All that wifey s*** is dead/ Put that s*** to bed." She continues ... "I'mma make 'em beg/ When I want some head."

The fallout from The Black Crowes' onstage political dust-up on Sunday didn't end with boos ... it kept rolling straight toward the exits.

Check out the video we obtained ... concertgoers can be seen popping up from their seats and streaming out of the venue following frontman Chris Robinson's controversial comments during the band's Tampa show.

The clip shows a steady flow of fans heading for the aisles while others remain seated as the concert continues. Several sections appear noticeably in motion as attendees make their way toward the exits -- no longer interested in sticking around after the tense exchange.

Chris Robinson got into it with fans at The Black Crowes' Florida concert ... beefing with folks who started chanting "U-S-A."

Here's the deal ... the band was performing Sunday in Tampa as part of their "Southern Hospitality Tour" when a visual thrown on a screen reportedly showed the band's Black Crowe character dressed as Uncle Sam.

A source tells TMZ ... before the band started playing "She Talks to Angels," the crowd started chanting "U.S.A."

That's when Chris addressed the crowd, saying ... "Thanks for the geography lesson."

When the crowd kept chanting, Chris added ... "I don't know what you have to be so proud of right now."

Round of applause for Waka Flocka Flame ... he says he's about to become a biological father for the first time!!!

Waka -- real name Juaquin James Malphurs -- just shared the happy news on social media, and it looks like he's having a son named after him.

The "Round of Applause" rapper shared an image of him holding a wooden decoration shaped like an oversized "J" inscribed with "Juaquin Jr."

Foster Sylvers, the standout child star of the 1970s family R&B group The Sylvers, has died ... TMZ has learned.

Foster's brother, Leon Sylvers III, tells TMZ he died in hospice following a battle with stage 4 pancreatic cancer. More updates will come from their sister, Pat Sylvers.

The Sylvers skyrocketed to fame in the '70s with hits like "Fool's Paradise, "Boogie Fever," and "Hot Line." The group had many iterations during their decade in the spotlight ... the above photo shows James, Foster, Edmund, Ricky, and Angie.

6:30 PM PT -- Ronald LaPread died following a brief illness, his representative tells TMZ.

Ronald LaPread -- one of the founding members and bassist for soul band the Commodores -- has died.

His daughter, music producer Soraya LaPread, shared the sad news on social media Saturday. She did not divulge any details of his passing, but NZ Herald reported he died following a "sudden medical event" in Auckland. Ronald had been living in New Zealand since the 1980s.

TMZ has reached out so Soraya and the Commodores for comment ... so far, no word back.

This singer is "The Voice" behind some massive hits ... but do you know who he is?!

We caught up with him at the Grammys last year, where he showed Kendrick Lamar some love after his big wins for "Not Like Us."

Morgan Wallen's song "180" might as well have described what he did to his piano last night ... because he flipped the thing almost completely over mid-show!

The country star lost his cool during the first night of his weekend at Empower Field at Mile High in Denver, Colorado ... when, while trying to sing his track, "Sand In My Boots," he experienced some technical difficulties.

Wallen couldn't seem to hear the piano ... so he tossed it instead. He then finished the rest of "Sand In My Boots" a cappella.

Vanilla Ice says President Donald Trump isn't the only politician who can book him ... he'd perform for Joe Biden, Vladimir Putin or pretty much anybody else willing to dance ... and he's not apologizing for it!!!

The "Ice Ice Baby" rapper joined us on "TMZ Live" Friday and told us he isn't sweating the controversy surrounding the upcoming Freedom 250 event in D.C. ... 'cause he's not big on politics and isn't bowing out like many of his peers.

Ice argues music should bring people together -- not divide them -- and he doesn't care who's signing the check or hosting the party. In fact, he tells Harvey he'd happily show up if Biden called asking him to perform at a family wedding.
