Where you at Diplo?! Katy Perry had no one to cuddle with on Halloween Eve this year.

The DJ's girlfriend posted a comical Throwback Thursday video on Instagram on Thursday, Nov. 6, of herself lip-syncing Celine Dion's rendition of "All By Myself" while still dressed as a Flamin' Hot Cheeto following Kate Hudson's Halloween bash on Oct. 30.

"When I was a sad Cheeto that no one wanted to cuddle at the end of the night," Perry captioned the funny video.

So where was Diplo, who helped celebrate the songstress' 30th birthday in Morocco, on Halloween? Perry's beau was busy DJ'ing at a show at Las Vegas' Surrender Nightclub.

The DJ, whose real name is Wesley Pentz, didn't fail to give Perry a subtle shout-out though. The following day, he Instagrammd a photo of himself dressed as a vending machine containing snacks, including Cheetos.

The couple have been linked together since first being spotted getting cozy at Coachella in April 2014.
