The super-secret nuptials, which even Kate’s parents didn’t know about, saw her Titanic co-star Leonardo DiCaprio walk her down the aisle.

“I can confirm that Kate Winslet married Ned Rocknroll in New York earlier this month in a private ceremony attended by her two children and a very few friends and family. The couple had been engaged since the summer,” a spokesperson confirmed to the UK’s Daily Mail.

While the parents of both 37-year-old Kate and 34-year-old Ned were unaware of the wedding, Ned’s father says, “Nothing would surprise me with those two”.

The couple reportedly met when both were houseguests of Richard Branson – Ned’s uncle - on exclusive Necker Island in the Caribbean in August 2011. When a fire broke out, forcing the villa's occupants to evacuate, Ned accompanied the actress and her children back to England, although she had arrived with on-off boyfriend model Louis Dowler.

The ultra-private actress has married in secret before, tying the knot with her second husband Sam Mendes in 2003 on an island in the Caribbean with just her daughter Mia and three friends.

Ned, who works for the space-travel branch of the Virgin empire and changed his name by deed poll from Abel Smith, has also been married before.
