Despite Martha Stewart's past jabs at Blake Lively's lifestyle website Preserve, the pair bonded on stage at the American Made event in New York City on Saturday.
The former "Gossip Girl" star look radiant as she posed for pics at the event, wearing a flower-covered long-sleeve white Michael Kors skirt and turquoise necklace. She paired the look with a cute Comes with Baggage "Doodle" clutch.
During the panel discussion, Blake gushed about husband Ryan Reynolds and told the story of when the couple first met Martha.
"When we met Martha, she was like, 'I'll ride motorcycles with you, Ryan,'" she told the audience. "That's the only woman that can creep up on my man and I would be okay with it."
Lively has been turning heads with her chic maternity style.
The expecting star was seen walking out of Stewart's event in another adorable outfit, where she put her growing belly on display in a navy knit Korovilas Eleanor dress and a black-and-white graphic Lindsey Thornburg trench. She paired the look with over the knee Christian Louboutin boots, wavy tresses and her signature radiant smile.
