Sure, Justin Timberlake is well known for singing about bringing "Sexy Back," but after three years with wife Jessica Biel, it doesn't seem like the "sexy" has gone anywhere.

Jessica tells Marie Claire magazine her theories on why they're going strong after Suit and Tying the knot.

She tells the magazine, "We have similar values: we believe in loyalty, honest. We like to have fun. We like a lot of the same things."

While opposites might attract sometimes, their son Silas has also brought them together. Jessica tells the magazine, "these little people come around, and they require so much, and your schedule is really not your own... and it's very clear that it's your life now revolving around this dude."

Parenthood is definitely something they both have high value for.
