Attention: Ned Rocknroll Knocked Up Kate Winslet
People Magazine confirmed with the couple's rep that Rose Dawson is indeed preggers.
"Kate and Ned are delighted," the rep added.
Rocknroll, whose uncle is Sir Richard Branson, legally changed his name from "Abel Smith" in 2008. The couple were married in a secret ceremony this past December, after meeting at Branson's Necker Island retreat in August 2011.
Winslet is mom to Mia, 12 (with Jim Threapleton) and Joe, 9 (with director Sam Mendes).
