Jon Snow has no chance of rekindling his love with Ygritte on “Game of Thrones,” but stars Kit Harington and Rose Leslie are back on in real life. Us Weekly reported the HBO actors are once again dating after a breakup last August.

A source told Us Weekly that Harington, 27, and Leslie, 27, started dating three months ago. “It’s casual right now, and they’re having fun,” the insider told the magazine. “They’re not moving in together or anything like that yet.”

The famous duo was together in 2012, but split in 2013. E Online reported last week that Harington and Leslie were spotted looking “quite friendly” when they arrived at Los Angeles International Airport, aka LAX, ahead of their San Diego Comic-Con panel for “Game of Thrones.” The actors were photographed walking “extra close to each other.”

Harington has been a fan favorite on “Game of Thrones” since the beginning of the series. His character, Jon Snow, Ned Stark’s bastard son, developed a relationship with Leslie’s character, Ygritte, in Season 2. The characters flip-flopped as prisoners -- Jon Snow captured by the Free Folk, and Ygritte briefly captured by the Night’s Watch. Jon Snow was brought back to the Free Folk’s camp after hatching a plan with his Night Watch leader, Qhorin, to infiltrate the Wildlings. He initially fought off his attraction to Ygritte because of his commitment to the Night’s Watch, but ultimately broke his vows of abstinence.

Ygritte was absolutely smitten with Jon Snow, and was devastated to learn he was still committed to the Night’s Watch. In Season 3, Jon Snow was forced to flee after his loyalty was questioned and Orell ordered his death. Ygritte chased after her former lover, hitting him with three arrows. However, her love for him led her to spare his life.

In Season 4, Ygritte vowed to get revenge for Jon Snow’s betrayal and warned the others in her group that his death would come only at her hands. The others doubted her because she had spared his life before, and they turned out to be right. During an attack on Castle Black, Ygritte killed a handful of Night’s Watch members before coming face-to-face with Jon Snow. A brief second of hesitation resulted in her getting shot in the chest by Olly. Jon Snow held her in his arms as she died. With her last few breaths, she reminisced about their love and uttered these final words: “You know nothing, Jon Snow.”

“Game of Thrones” will return to HBO for Season 5 in April 2015.
