The Hollywood heartthrob has been dating the former WWE Diva for around three months and he admits he would be worried if they ever got into a fight, because she's much stronger and taller than him.
He said: "She's very tall. She can kick my ass. She can take me two out of three falls."
However, George says he doesn't have to worry too much about feeling the wrath of Stacy's temper because she's such a lovely person.
He said: "She's a nice girl. She really is."
The pair have been dating since August and are having lots of "fun" with neither George, 50, and Stacy, 32, worried about where the romance is heading.
A friend of the ex-wrestler said: "They don't really know where things are going to go, and it doesn't bother her. They're just having fun, and Stacy is enjoying every moment of it."
However, George - who has made no secret of how he loves being a bachelor - is quite keen on Stacy and recently introduced her to his parents.
An insider said: "It's a big deal and Stacy knows it. She really took to George's mom and said she's a sweetheart.
