Kate Winslet secretly wed beau Ned Rocknroll, nephew of Virgin Atlantic tycoon Richard Branson, earlier this month, People reported. But here's the detail that'll make you swoon: The ceremony was so hush-hush that the happy couple's parents weren't even informed — but Kate's "Titanic" co-star, Leonardo DiCaprio, was. And he reportedly walked her down the aisle, giving her away to her new husband. Cue happycry!

This is the third marriage for 37-year-old Winslet, and the second for Rocknroll (born under the name Abel Smith, but legally changed for reasons of maximum silliness, we assume). The two were reportedly married in front of Winslet's two children and a few friends and family.

Winslet and DiCaprio have been spotted together many times through the years since co-starring in 1997's "Titanic," and even had an onscreen reunion in 2008's "Revolutionary Road," directed by Winslet's second husband, Sam Mendes.

We have just one lingering question about Kate's undercover nuptials: When they did the whole "speak now or forever hold your peace" thing, did Leo even think for a second about reminding Kate of that whole "Never let go" routine? Betrayal! (Yes, we know, they were acting, but still!)
