End of the Line for Kristin Davis and Aaron Sorkin?

Is it a wrap for Kristin Davis and Aaron Sorkin? In Touch claims the summer fling between the actress, 47, and the prolific "Newsroom" overlord, 51, has been flung due to personal and professional commitments.

"They're very different people," a source tells the tab. "She's focused on raising her daughter, Gemma, and he's working on his show."

Two months ago, Davis and Sorkin made an affectionate debut at the Los Angeles premiere of "The Newsroom," trading kisses and embraces on the red carpet.

"He is obviously really smart," an insider told E! News of the attraction between the pair, who were first linked in May, "and Kristin is very intelligent, too. They have a lot to talk about."

Neither party has confirmed that the conversation has petered out, but the In Touch spy insists, "They'll definitely remain friends."
