De Matteo, 35, and Jennings, 27, a Nashville-born musician and son of the late country legend Waylon Jennings, have been dating for six years.
"I never thought I'd get along with a New Yorker," Jennings told PEOPLE in 2005. "But in her heart, she's a redneck too." Besides, he claims that de Matteo "has the best taste in music."
News of the pregnancy was first reported by the New York Post's Page Six.
De Matteo famously played the doomed Adriana La Cerva on The Sopranos before moving from New York City to Los Angeles to star opposite Matt LeBlanc as Gina Tribbiani on NBC's Friends spin-off Joey.
Of the new job, she told PEOPLE in 2004, "I'm really glad I don't have to go into work and cry for six months. Palm trees. No heroin. No beating."
Jennings, who released the album Electric Rodeo last year and played his dad in the 2005 Johnny Cash biopic Walk the Line, was born Waylon Albright Jennings. How did he get his nickname? His mother, singer Jessi Colter, told him that she borrowed it from a friend's son – but he isn't so sure.
"My dad said I got it because I pissed on a nurse after I was born," he told PEOPLE in 2005. "I like his version better."
