Blake Lively is one sexy mama-to-be!

On Monday, the pregnant actress flaunted her cleavage and her growing baby bump in a curve-hugging yellow Gucci dress that featured a plunging neckline.

Hubby Ryan Reynolds didn't leave his wife's side on the red carpet at the 2014 Angel Ball as the twosome posed together looking happy and almost giddy with excitement. For his part, the Canadian actor looked dapper in an all-black suit with a bow-tie—an accessory he also wore on Saturday in Toronto when he was inducted into Canada's Walk of Fame.

Their joint appearance is the first time the couple have attended an event together since Blake's pregnancy was announced earlier this month. The 27-year-old former "Gossip Girl" actress is expecting the couple's first child and the mom-to-be couldn't be more excited.

"It's something that I've always wanted ever since I was a little girl," the "Preserve" founder said. "I never knew what I wanted to do for a living, but I knew I wanted to have a lot of kids because I had come from a big family, so it was always important to me."

She's also been having a good time showing off her maternity style in outfits such as a cute blanket coat, an animal-print jumpsuit and a floor-sweeping gown.

Looking good, Blake!
