"Covert Affairs" starring Piper Perabo (Anne Catherine "Annie" Walker), Christopher Gorham (August "Auggie" Anderson), Peter Gallagher (Arthur Campbell), Hill Harper (Calder Michaels), Nic Bishop (Ryan McQuaid), Anne Dudek (Danielle Brooks) and Kari Matchett (Joan Campbell), has been cancelled by USA Network. The show aired its Season 5 Finale, episode 16 "Gold Soundz" last Dec. 18, 2014. Read on to learn more about it.

According to Deadline, USA Network decided not to renew the spy drama because of rising costs in producing the show which include the talent fees of the stars and big budget locations around the world. The series' lower ratings in Season 5 also came in to play with the network's decision to axe it. Entertainment Weekly reports that "Gold Soundz" only drew 1.59 million viewers.

The "Covert Affairs" Season 5, episode 16 "Gold Soundz" turned out to be not just a season finale, but also the series finale. In the end of "Gold Soundz," Annie was given two choices: to accept Ryan McQuaid's marriage proposal or to join Joan's new CIA task force. Annie just said the words "Got it." But, it is unclear what Annie chose between the two options presented to her. As for Auggie, he planned on retiring as a spy.

The stars of "Covert Affairs," took to social media to thank their supporters. Christopher Gorham expressed his gratitude to the "Covert Affairs" fans in his personal Twitter account.

"Thank you. Thank you. Thank you. It's been 5 amazing seasons and we owe it all to you. Next up, #ThroneofAtlantis , and then..." Gorham tweeted.

Meanwhile, Nic Bishop posted a picture of him and Perabo on his official Instagram account. Of course Piper Perabo, also known as Annie, tweeted about saying goodbye to "Covert Affairs." Check out her tweet below.

"Thanks for all love for .@CovertAffairs I will miss it but am so happy to have made so many great friends through it. Love you guys, xp," Perabo posted on her official Twitter account.
