Cameron Diaz and Benji Madden may have celebrated their first wedding anniversary in early January, but it's clear that the couple is still very much in the honeymoon phase of their marriage. Diaz recently stopped by Andy Cohen's Sirius XM Radio show, where she revealed how she knew Madden was The One.

"You just know when you know," the actress-turned-author told Cohen, although she admits she didn't always understand that notion. "I was always like, 'What does that mean … what does that mean?' Then I was like 'Oh, I get it, you just know when you know, like you're my husband." Sweet!

"You realize like, 'Oh right, this is what the real thing is, this is what real love is and this is what commitment and devotion is,'" she added. "This is the person that you build your life with, and for me, it's like the rest of everything else just kind of like dissolves."

So how, exactly, did Diaz know Madden was the one? "The first thing I saw when I first met my husband, I was like he's hot!" she said. "We had just never been in the same circle, then I saw him like a year later, I saw him again, and I was like wait a second, still hot." The second time happened to be when good friend Nicole Richie and her husband Joel Madden brought Benji along to a barbecue at Diaz's home. The rest, as they say, is history. Tune in to Cohen's Sirius XM Radio show on Friday morning at 8 a.m. ET to hear the full interview.
