(Cover) - EN Showbiz - George Clooney has reportedly taken his relationship with Stacy Keibler to the next level and introduced her to his parents.

The 50-year-old actor and the former WWE wrestler have been dating since late summer but he has already taken her to meet his father Nick and mother Nina, according to Life & Style.

George and Stacy have not yet made an official appearance together but things are said to be steadily getting more serious.

"It's a big deal and Stacy knows it," an insider told the publication. "She really took to George's mom and said she's a sweetheart."

George apparently told Stacy that he does not introduce all his girlfriends to his parents and Stacy has told a friend that her chemistry with the Up In The Air actor is "off the charts."

"A lot of people thought it was going to be a fling," a friend of George's said. "But it's not it's at the serious point."

Stacy, 31, did not make any red carpet appearances with George during his recent trip to the Venice Film Festival but will reportedly meet up in Los Angeles before the actor goes to the Toronto Film Festival later this week.

The blonde beauty has been coy about talking about her relationship with the eligible bachelor but says she is definitely a woman that men like to be around.

"Anybody that knows me knows that I'm definitely a guy's girl," she told People magazine. "I just can really adapt to any kind of environment."

"So I can get all dressed up and have a great girls' night out and then can also be playing beer pong with the boys.

"I'm always happy. Anybody that knows me knows that I'm a very happy person." (C) Cover Media
