Is that wedding bells we hear? Maybe, seeing as though Cameron Diaz and her boyfriend Benji Madden have reportedly been discussing marriage.

The unlikely couple was first rumored to be dating earlier this year in May. However, the news wasn’t confirmed until Madden’s sister-in-law, Nicole Richie, confirmed the news on an episode of Watch What Happens Live. Richie even admitted that she was the one to set them up.

“I am a devoted sister-in-law,” Richie, who is married to Benji’s twin brother Joel Madden, said of her brother-in-law. “I’m happy for anyone who is happy, and I want everyone to be surrounded with love.”

Since then, Diaz and Madden have been spotted around New York City holding hands, and Madden is reportedly living with Diaz since he spends so much time at her Los Angeles home. “They look very happy together,” an insider close to the couple said. “Cameron hasn’t looked this happy for years.”

So, is a wedding in the near future? The insider revealed that the Sex Tape actress and Good Charlotte vocalist have been discussing the possibility of saying “I do.” “It’s early, but they have talked about marriage,” the insider explained.

Madden even met his potential in-laws on the couple’s recent trip to Florida.”It seemed important to Cameron that Benji met her family, and she looked very proud to introduce him to everyone,” the insider added. “They were very sweet to each other, constantly kissing and flirting. It was obvious that they had a great vacation.”

Diaz was previously in relationships with Carlos de la Torre, Matt Dillon, Jared Leto, Justin Timberlake, and Alex Rodriguez. Madden was previously engaged to Sophie Monk for years before splitting up in 2008.
