Biel tells how her hubby proposed

Justin Timberlake’s marriage proposal to Jessica Biel was sweet like candy - but it didn’t bring “Sexyback.”

The “Candy” star, 40, who will celebrate her 10-year wedding anniversary to Timberlake, 41, in October, recalled the “most lovely, surprising, hilarious” proposal Wednesday on “The Late Late Show with James Corden.”

“We were in Montana on a piece of property that we owned at the time. We had snowboarded all day, it was in the middle of the winter, waist-high snow, we were head-to-toe snowboarding outfits,” Biel recalled.

“And we go up to the property to just check out how the foundation is looking and all this stuff. And all of a sudden, he gets down onto his knees and just sinks into the snow. And then he looks up at me and pulls up this ring.”

Corden, 43, joked that skiing with a ring on you “can only backfire” unless “you’re some kind of maverick.”

Biel and the pop star tied the knot in October 2012. Together, they share sons, Silas, 7, and Phineas, turning 2 this summer.
