Angie Harmon and Jason Sehorn are amicably separating after 13 years of marriage, her rep tells PEOPLE exclusively. 

"For the sake of their children, they ask for respect and privacy as they navigate this time in their lives," her rep says. 
 
During a recent interview with Your Tango, the Rizzoli & Isles star freely admitted that marriage is nothing short of hard work.
"You have to be really considerate of each other, really kind to each other," she shared with the publication. "It's a lot of work, really." 
 
 Her engagement happened live on TV during an episode of The Tonight Show with Jay Leno. Back in 1998, Sehorn surprised his then-girlfriend by walking out onto the stage and getting down on one knee.
 
In 2011, Harmon, 42, spoke about the difficulties of splitting her time between Los Angeles, where her show is filmed, and Charlotte, North Carolina, where thefamily is based. 

"We don't get out Friday nights early enough to catch a flight home," she toldYour Tango. "So I'm here [in L.A.]. We sometimes meet in Texas, a 2½-hour flight for both of us. I miss my kids, so it's hard, but my children are so understanding." 

The former Law & Order star also admitted she and Sehorn, 43, strived to keep their marriage strong despite the distance.
