Talbot and Guerro -- a 30-year-old model and T-shirt designer from Columbia -- reportedly met last December at his 30th birthday bash in Brazil.
While the couple has yet to set a date for their wedding, Talbot saidTop Chef host Padma Lakshmi and judge Tom Colicchio will most likely be in attendance.
"Tom and I talk all the time," Talbot told People. "We're friends."
After finishing third on Top Chef's Fall 2006 second season, Talbot opened The Surf Lodge in Montauk, NY -- where he said Guerro is a regular visitor.
"She takes care of me in many ways," he told People. "I'm quite lucky."
