That was fast! Just four months after Kate Winslet's rep confirmed to Us Weekly that the Oscar-winning actress was expecting her first child with husband Ned Rocknroll, the pregnant British actress rocked a very large bump at the premiere of her film Labor Day

Though the vibrant scarlet red Jenny Packham gown was stunning and flattering, Winslet, 38, looked like her "labor day" could be any moment now. The Mildred Pierce star is due at the end of the year, and this baby will be her third child. By all calculations, Winslet should be about seven months pregnant. 

As a seasoned red carpet pro, Winslet looked flawless at the BFI London Film Festival as she posed with her hair swept back revealing a pregnant glow. 

Winslet is already mom to son Joe Alfie Winslet Mendes, 9, with ex-husband Sam Mendes and daughter Mia Honey Threapleton, 13, with ex-husband Jim Threapleton

The Brit was married to Threapleton from November 1998 to December 2001 and to Mendes from May 2003 to March 2010. 

Us Weekly exclusively revealed the famed actress had secretly wed Rocknroll -- the eccentric nephew of Richard Branson -- in December 2012 after almost a year of dating.
