The screamo singer captioned the post: “Had a great time hanging and finally meeting @travisbarker (who has always shown me love and gave me advice) and @dark_waves!

“Had no idea we were gonna cook haha! it was insane watching them work. Truly grateful.”

The first photo captured Nathan and Travis, 47, standing inside the rockstar’s home – that he shares with wife Kourtney Kardashian, 44.

The pair posed in front of the Hulu stars’ Christmas tree, which still featured a Halloween theme due to a giant skeleton being positioned beside it.

The second snapshot showed Nathan and singer/songwriter Nick Long of Dark Waves working inside Travis’ studio.

In the background, behind all the sound equipment, a penis-shaped pillow could be spotted wearing a Santa hat.

The pillow appeared out of place among all the high-tech equipment but still seemed to fit in with the rockstar drummer’s raunchy taste.

A third pic showed Travis watching the sound booth and monitoring the recording equipment from inside the studio.

In the comment section, fans congratulated the underground artist for working with Travis.

One person wrote: “Good for you man! Yer killin it!!”

Another added: “This is legendary.”

A third person wrote: “awesome to see Travis supporting the underground for a while now!”

And a fourth commented: “So happy for you. You deserve it!”

CONCERNED FOR KOURT

Earlier this week, Kourtney posted about her mental health while hiding away and not posting with her newborn son.

The eldest Kardashian sister posted the Instagram photo via Poosh’s page and fueled rumors she’s hiding with her newborn son, Rocky.

Kourtney’s brand uploaded a Story of Tracee Ellis Ross leaning out of a bathtub.

The star had her hair tied up on the top of her head and went makeup-free.

Tracee leaned her head on her hand and looked seemingly upset as she looked at the camera.

The lifestyle brand added the caption: “Stressed? Depressed? Anxious? Overwhelmed? All of the above.

“Here are 10 simple self-care hacks for stressful times.”

This photo is the first regarding Kourtney’s health since the birth of her baby boy, Rocky, in November.

Reports have said Kourtney and Travis Barker are keeping Rocky in hiding and away from family to enjoy time with him alone.

A source close to the family said that the Barker-Kardashian clan has refused family visits.

ON THE ROCKS-Y

Kourtney has been reportedly keeping a strict “invite-only rule” for anyone coming to visit her baby boy, The U.S. Sun exclusively learned in early November.

According to an insider, even Kourtney’s sister Kim Kardashian, 43, still hasn’t met her new nephew.

The source exclusively told The U.S. Sun: “Kourtney is going to be introducing the new baby to her family on an ‘invite-only’ basis.

“[Kourtney] and Travis have communicated that they will be taking ‘family only’ time for the newly blended family and for Kourt to rest, and then they will be inviting the extended family over on an individual basis,” the insider explained.

“Kourtney has said it’s a germs thing – to protect the baby and not expose him to any risk – but it’s, like, part of her new strategy to keep everyone at arm’s length,” the insider claimed.

CONTROLLING?

This Instagram Story came after Travis was accused of displaying potentially controlling behaviour.

Some fans have previously criticized Travis for being controlling over Kourtney and their son after they named their son Rocky on Travis’ wants.

In July, Travis said he wanted to name his son Rocky Thirteen after his favorite musician, the guitarist for Suicidal Tendencies, and his favorite number.

He told his daughter Alabama: “I like Rocky Thirteen. That’s this name that’s just been going through my head lately.”

The rocker later confirmed that he and Kourtney were naming their son Rocky Thirteen Barker.

Another added: “Her allowing this baby’s name to be Rocky Thirteen will confirm for me that he is controlling.

“Rocky, that’s one thing. Not my vibe, and not the real Kourtney’s vibe, but I could see it. THIRTEEN? Baby, this ain’t stranger things!!!!”

A third posted: “Yeah I don’t like that the new kid’s name is completely Travis’s interest.

“Kourt was the only one that had normal names for her kids and then Barker wanted Rocky 13.

“He seems very controlling and the only reason why Kourtney accepts it, is because to her, he loves and is devoted to her.”
