Years after her famous fallout with Lauren Conrad, Heidi Montag finally has a new female BFF: Ashley Dupre!

The Hills alum bonded with the former escort while filming their new reality show Famous Food (VH1, Sundays, 10 p.m. ET), which features celebs like The Bachelor's Jake Pavelka, Three 6 Mafia's DJ Paul and Juicy J and ex Real Housewives of New Jersey star Danielle Staub competing to win a share of a restaurant.

"Ashley's my absolute favorite person hands down on the show," Heidi tells In Touch. "She’s the sweetest, nicest person. She’s one of my favorite friends I’ve ever had in my whole life. I love Ashley! If it weren’t for her, the show would have been a lot different for me. She’ll be one of my best friends for the rest of my life."

Hmm — Heidi's husband, Spencer Pratt, may be jealous!
