Harris, who played Lane Pryce on the AMC hit for three seasons, wed his longtime girlfriend, Allegra Riggio, in Miami on Saturday, Us Weekly reports.
"Just married. <3 #TeamHarris #Jally #MarriageEnsued," Riggio tweeted shortly after their nuptials, along with a picture of the newlyweds.
The couple met in 2009 at the stand-up comedy show of a mutual friend, according to Us. They were engaged in June.
