Are Gerard Butler and girlfriend Morgan Brown engaged?

The designer was snapped wearing what seemed like a large diamond on her finger on Sunday which sparked engagement rumors.

"She showed off the impressive ring as she was spotted taking in a solo stroll through Malibu, California," said Daily Mail.

"Morgan looked casual for her walk, sporting a loose-fitting white T-shirt which showed off a hint of her toned stomach," the publication added. "She coupled that with a pair of light wash destroyed denim jeans and a coordinating pair of white, worn Converse sneakers."

Gerard Butler's girlfriend is an interior designer who owns Morgan Brown Designs. She also used to model.

"Morgan got into the interior design business after buying her first house in her 20s and flipping it, realizing it was a passion. She quickly turned her passion into an occupation," Just Jared said. "Morgan's mom was model Karen Brown, known for dating legendary actor Peter O'Toole."

Gerard Butler and Morgan Brown started dating last summer and according to Who Say, their romance only grew in recent months until they moved in together in December last year.

They went public with their relationship when they were seen kissing in California in November last year.

"Gerard is a one-woman man now. They just moved in together. And now they're talking marriage," a source said. "He says Morgan also put him on a regime of green juices, and since then, he's lost weight and he's feeling healthier."

Gerard Butler and girlfriend Morgan Brown were snapped kissing at the New Orleans Saints match against the Carolina Panthers at the Mercedes-Benz Superdome on Dec. 7 in New Orleans.

"The 45-year-old actor got hot and heavy by giving Morgan a kiss on the sidelines. Gerard was also spotted taking photos with fans as he watched the Panthers," the report said.
