The 43-year-old America's Got Talent judge Instagrammed a handful of shots from the festival in Black Rock City, Nevada, including a sweet pic with her boyfriend, art curator Vito Schnabel.
"ILY," she captioned the shot, adding the heart emoji and red lips. Klum and the 30-year-old started dating in February 2014
and have been practically inseparable since.
The rest of Klum's snapshots feature various Burner installations, including elaborate floats and strange art pieces. "Burning Man ....WOW INCREDIBLE," she captioned one photo. (You had to remove all those bonkers emojis to get the last word.)
Cara Delevingne, Katy Perry, and Paris Hilton were just a few of the other celebrities in the desert for the fest. See who else was there -- and what they wore -- in the video below.
