A former Big Apple model who once appeared in a shoot alongside Gisele Bündchen allegedly kicked a tot to the ground in a Kansas grocery store while shouting racial slurs, authorities allege.

Chisel-jawed Trace Riff was charged Monday for the ugly Dec. 31. attack — where he allegedly stomped on a black one-year-old boy while declaring himself a white supremacist and using the n-word.

Riff, 31, — who once strutted his stuff for the likes of Hugo Boss and Emporio Armani — “sounded like a madman” as he ranted, the child’s mother, Lashantai Whitaker, told the Wichita Eagle.

In his first court appearance Monday, Riff appeared via video monitor in a lemon-yellow prison jumpsuit, mumbling incoherently as his long, stringy hair fell over his face.

That’s a far cry from 2005, when the Oklahoma native appeared with his arms wrapped around Tom Brady’s future wife in Harper’s Bazaar.

When he started his career in New York City that year at 18, “Everybody was trying to sign him,” his paternal grandmother, Twila LaRue told the paper.

“He is a real pretty boy and the modeling agencies were just after him,” she said.

He walked in runways for Marc Jacobs and Louis Vuitton and traveled all over Europe, reveling in the glitz and attention, according to his family and MySpace page.

But his life started spiraling out of control when he began using drugs, his family said. He moved back to Oklahoma and couldn’t find work, his granny told the outlet.

“I think he just wants to be out of reality,” LaRue said.

For years, he’s been homeless in the Wichita area, and his last gig was as a plumber, according to court records.

But Riff still believes he’s Hollywood-bound and has a “delusional feeling on entitlement,” LaRue said.

He has a long rap sheet, most recently for felony possession of meth on Jan 3.

Hours after the grocery-store attack, Riff was arrested and then released. He was collared again Monday, this time on attempted aggravated battery charges.

“I’m happy,” said Whitaker, the mother of one-year-old Jhavii Fry. “Because I though they were going to blow it off.”

Riff is being held in Sedgwick County Jail on $100,000 bond. His next court appearance is Jan. 14.
