Most recently, Cameron has been consistently rocking a thick gold ring with dazzling stones. Next to it sits a thin gold band.

"It happened a few nights ago," a Madden source told People of the proposal. "All of Benji's friends are aware and happy for him. ... Her mom is a fan of him as well and gave her blessing."

"Everyone thinks it's wild but are so happy for them," a source told Us Weekly late last week. "Benji always tends to fall in love easily, but this time it's for real and he landed a great girl. They obviously both make each other incredibly happy and there's nothing better than that."

In the January issue of Cosmopolitan, Cameron deflected engagement questions, but discussed her thoughts on love (her previous high-profile relationships include Justin Timberlake, Alex Rodriguez, and Jared Leto).

"You have to find someone in the same place as you are. Timing is everything," she said. "If you get into a relationship where you want something the guy doesn't want, it's never gonna work. You're never going to get him to be in that place. No matter how old you are, finding the guy who's in the same place as you are and wants to show up is the only way a relationship works, period."

Months earlier, the actress discussed her views on kids and marriage.

"I'm not looking for a husband or marriage or not not looking for that stuff," she explained to Marie Claire. "I'm living, not thinking what I should or shouldn't be doing with my life."

She continued, “We live in a society where everyone has kids, so they want other people to have kids. There is this culture that says celebrities are supposed to be just like us, so people think, 'I have children, why doesn't she?' But I'm not going to do something because it’s expected. If a family happens, then it happens. If children come to me, then I would do that, but I'm not someone who feels like she has to do something because it's expected."

Nicole Richie played matchmaker for the couple, although they knew each other for years before giving their relationship a go.

"I approve of anything that's going to make Benji happy," Richie told Andy Cohen back in July (she is married to Benji's brother, Joel Madden). After divulging she was the one who set them up, Nicole added, "I'm going to take responsibility for everything!"
