New mom Kate Winslet showed off her stunning post-baby figure in a little black dress on Monday (17Mar14) as she unveiled her star on the Hollywood Walk of Fame.

The event marked the British actress' first public appearance since becoming a mom to her third child, son Bear, in December (13) - and it took place just hours after Hollywood was shaken by an early-morning earthquake, which registered 4.4 on the Richter Scale.

The Oscar winner, who was saluted by her Titanic co-star Kathy Bates and director James Cameron, told fans she was thrilled that so many people had come out to honor her so soon after the tremors.

She told the crowd gathered on Hollywood Boulevard, "I'm completely overwhelmed by the number of people that are here today. I honestly had no idea this was going to be quite such a well-attended event, especially after the earthquake this morning, which frightened me quite a lot actually."

She added, "I made for a door frame with my breast pump in my hand.”

Winslet's star was the 2,520th unveiled on the Hollywood Walk of Fame.
