Matt LeBlanc began dating model Melissa McKnight in 1997, via Bustle. He proposed to McKnight a year later, and the couple dated for five more years before getting married in 2003. In 2004, McKnight gave birth to daughter Marina. However, LeBlanc unexpectedly called it quits in 2006, according to People. McKnight's longtime friend, Kelly Phillips, told People, "It was very sudden. She was absolutely blindsided by what transpired."

Not long after, LeBlanc admitted that he was romantically involved with another woman. The woman turned out to be Andrea Anders, LeBlanc's co-star on the "Friends" spin-off "Joey," per Bustle. LeBlanc and Anders dated for eight years before splitting up in 2015.

That same year, LeBlanc reportedly met TV producer Aurora Mulligan on the set of "Top Gear," via The Sun. LeBlanc and Mulligan weren't linked to each other until 2016, but they soon appeared to be inseparable. The couple likes to maintain a low-profile, but they are allegedly still together.
