Dexter star Jennifer Carpenter has been secretly dating married singer of The Avett Brothers, 32-year-old Seth Avett, according to RadarOnline. Even though he is still married to wife Susan, Avett has been seeing 33-year-old Jennifer since 2011.

According to an insider close to the band, the two were involved in a long-time secret affair that ended up destroying his marriage.

“Shortly after Jennifer’s split with Michael, she began seeing Seth. She would fly all over to his concerts to be with him,” the source told Radar. “No one saw this affair coming from those closest to Seth, but he finally left his wife last winter to be with Jennifer.”

In an interview just 2 months ago, Seth’s wife Susan did not mention their separation. But on Tuesday he formally made the announcement on his band’s website.

“The affair was really hard on Susan, and even the band,” the source told Radar.
