The 33-year-old former wrestler has been dating the hunky 51-year-old actor since July 2011 and even though he has grown a thick bushy beard, she is still crazy about him.
When asked what she thought about his facial hair, Stacy told E! News: ''I love it.''
Things have gotten serious for the couple and after spending last summer together in George's home in Lake Como, Italy, she moved in to his Los Angeles bachelor pad.
A source said: ''She's 100 per cent moved in with him, she spends her summers at Lake Como in Italy and all her stuff is at his place in Los Angeles.
''While she maintains a small rent controlled apartment in West Hollywood, she uses it as a storage space for mementos and personal items. All her clothes are at George's and she never goes home.''
George reportedly believes the blonde is the perfect woman for him because she isn't clingy like his past girlfriends.
The insider added: ''Stacy is his dream woman. She doesn't call to check in. He calls her more than she calls him.''
