Cougar alert!

Kris Jenner and former Bachelor Ben Flajnik are hooking up, and have been since shortly after his appearance on her talk show Kris last July, Us Weekly reports.

The 58-year-old momager and the 31-year-old dating show star are trying to keep their fling a secret, but they've been spotted hanging out in N.Y.C., driving around Calabasas together in her white Bentley, and enjoying date night at the Kanye West concert in Oakland.

"They started hanging out. It got romantic right away," a source told the mag.

The Keeping Up with the Kardashians star even tried helping the Sonoma winemaker with his business by filming an episode of their reality show at his winery.

Flajnik, for his part, is denying the romance rumors.

"Here we go again. Hey @usweekly maybe put a call into me once and a while for some fact checking. Sincerely, #TheTruth," he tweeted after the cover story emerged.

We're dying to know what Bruce thinks of this!
