Dua Lipa may be done with her “Radical Optimism” tour, but she clearly kept the vibes alive … playing hype woman for fiancé Callum Turner, who looked like he needed a serious vaycay pick-me-up.

Check out these pics — Dua was spotted going full comfort mode, wrapping her arms around Callum as he looked seriously down in the dumps this week in sunny Mexico, trying to figure out what had him so bothered.

Callum looked seriously bummed — but with how caring and tuned-in Dua was, it definitely didn’t seem like the blues had anything to do with trouble between the two.

Saturday night was a double takeover … rap artist Compton AV took over one bus, while DJ Sky from “Baddies” held it down on the other — and it turned into a full-on Christmas Bus Battle when the buses rolled past each other to see which one was more lit!

Compton AV was an incredible host … not only hyping the crowd, but delivering live performances of some of his biggest hits — including “Slid’N” — live on the bus. His bus, complete with a mobile billboard, followed us for an epic, on-the-move concert moment.

DJ Sky looked stunning and had passengers swooning as she led her bus to some of the best bars in town, including The Burgundy Room, one of the coolest, grungiest dive bars around. Both buses then hit Beaches in West Hollywood — not to be confused with Beaches Tropicana — where we got free shots and danced the night away.

To top it all off, Compton AV’s bus had a special guest, TikTok star Gigi, who came out to support him. She even posted a “TMZ After Dark” video from the night, which racked up more than a million views.

The surviving loved ones of Rob and Michele Reiner have a little more closure today … the couple’s death certificates have been released.

TMZ obtained the late couple’s certificates from the Los Angeles County Public Health Dept. … while they list some information already publicly known — multiple sharp force injuries as their causes of death — the gravity of the documents is still heavy.

They were both cremated at Mount Sinai Mortuary.

Rob and Michele’s deaths were previously revealed as homicides from “multiple sharp force injuries.” The certificates describe how the injuries occurred … “with knife, by another.”

As you know … Rob and Michele were found dead December 14 in their Brentwood home.

Rob and Michele’s bodies were found by their daughter, Romy, and she told police her brother, Nick, lived with their parents and was “dangerous” and should be considered a suspect.
