The baby was born on Oct. 6. Baker and Fuller, who are based in Los Angeles, got married in 2001.
The couple were notorious for their bickering and seemingly hostile relationship on the reality show, but artist Fuller – who was a 1996 Playboy Playmate of the Month – told PEOPLE in January 2005, "It was a great experience, despite how negative it looked."
Said Baker, 43, a filmmaker and spa owner, "I didn't like the person who was up on the screen. I think I am a better person than that. I don't want to make excuses for being the villain – I have to take responsibility for it."
After their stint on The Amazing Race, the couple also competed on Battle of the Network Reality Stars and Fear Factor, according to their official Web site.
