Gerard Butler has been dating his girlfriend Morgan Brown for a year now, and according to Dish Nation, the actor is reportedly head-over-heels for his main squeeze.

Gone are the days when Gerard Butler was still known as a Tinseltown playboy after being linked to Jennifer Aniston, Naomi Campbell, Cameron Diaz, Jessica Biel, Lindsay Lohan and reality star Brandi Glanville.

The actor's girlfriend, who's a Los Angeles-area interior designer, has purportedly made a loyal man out of Gerard Butler.

"Gerry and Morgan are a lovely couple and it's been smooth sailing since the moment they got together," an insider told the website.

"He's absolutely head over heels for her and thinks he may have finally found the one. Gerry's taking things slow, but very serious with Morgan."

"They don't do a lot of the typical Hollywood things. You won't see them hitting a red carpet together. Instead they're at a Sunday barbecue on the beach with a close-knit group of friends. She grounds him and they truly bring out the best in each other."

Even Gerard Butler's mom, Margaret, approves of his girlfriend.

"Margaret is tired of the endless string of women she's met over the last decade only to have those relationship fizzle out," the source told Dish.

As serious as he is in his relationship with his girlfriend, Gerard Butler even suggested they move in together.

"Even though this time Gerry insists his relationship with Morgan is the real deal, and that they've actually moved in together, Margaret is telling him to put his money where his mouth is and call her once he's put a ring on it!"

Gerard Butler and his girlfriend were last spotted together in a lingerie store in West Hollywood a couple of weeks ago where the actor seems to have treated Morgan to luxury underwear, according to Daily Mail.
