Kate Hudson Wears New Diamond Ring, Holds Baby Bump in First Appearance Since Pregnancy Reveal

Kate Hudson is absolutely glowing!

The 38-year-old actress attended the opening ceremony of a Harry Winston store in Hong Kong, China, on Monday, marking her first red carpet appearance since revealing she's expecting a baby girl with boyfriend Danny Fujikawa. Hudson wore a black lace slip dress and heels, but it was her choice of jewelry that has people talking. Hudson accessorized with a diamond ring on her left hand, sparking speculation of a possible engagement.

However, ET has learned that the emerald cut diamond rock band on Hudson's hand was on loan from Harry Winston for the event only. 

In addition to frosting herself, the How to Lose a Guy in 10 Days star also cradled her baby bump on the red carpet, posing to the side for cameras.

Hudson revealed she was expecting her third child earlier this month, sharing the gender reveal on her Instagram. The actress is already a mother to 14-year-old son Ryder with musician Chris Robinson, and 6-year-old son Bingham with Muse frontman Matt Bellamy.

ET recently spoke to Hudson's close friend, Erin Foster -- who's also Fujikawa's stepsister -- about the emotional gender reveal.

"We're just like, its such a beautiful thing -- our stepbrother and Kate getting together after 20 years of friendship has been such a beautiful thing -- and then they were hoping so badly they were gonna have a girl, and then when they found out they were having, and she did not know until the balloons popped and pink came out, and it was just, it was just too much," she gushed. "It was amazing."
