American reality TV star Kris Jenner had been reportedly missing sex while she was still married to Bruce Jenner.

According to Hollywood Life, the Kardashian matriarch is having a great time with her new boyfriend Corey Gamble.

"Kris has a very strong sexual appetite and she says she's basically been starving for sex," a source close to Kris told the website.

"Her sex life with Bruce died a long time ago, she's had some hook-ups here and there but this is the first time that she's been having regular sex in years and she can't stop bragging about it," the insider added.

Kris and Gamble were first spotted together while dining at Casa Vega restaurant in Sherman Oaks last month.

The 41-year-old, also incidentally Justin Bieber's co-manager, joined the 59-year-old Keeping Up With The Kardashians star on a private jet to Las Vegas for Kim Kardashian's birthday celebration two weeks ago.

"She says she feels alive again," the source continued. "It's all she wants to talk about, she even talks about it in front of her kids."

Khloe Kardashian had previously gushed over her mother's new boyfriend.

"Corey was over last night and he's great. I love him," Khloe told E! News. "He's so sweet and my mom is really happy."

"I like to see her in such a positive, happy state," she added. "It's a good Kris Jenner."

On 22 September Kris filed for divorce from Bruce, 11 months after they announced their split.

Bruce has also moved on in his love life and is reportedly dating Kris's former assistant and longtime friend Ronda Kamihira.
