Blake Lively's son got a boob cake on his first birthday; actress says, 'What do they want at 1?'

Blake Lively made a unique cake to celebrate her son Olin’s first birthday. During an interview with BBC Radio 2’s 'Zoe Ball and Friends', the 36-year-old shared the story behind the "boob cake" she baked for the occasion.

Known for her love of baking, Lively explained that she has a tradition of adding a playful twist to her birthday cakes. For Olin’s milestone birthday, she decided to make a “boob cake” and the reason will leave you in splits.

“My birthday cakes always have a little bit of a sense of humor,” Lively told host Zoe Ball, 53. “For my baby, I just did a giant set of tits,” she added with a laugh. The It Ends with Us star joked that this cake might be something that will “haunt him for life,” but since Olin couldn’t yet express his preferences, she thought, “Boobs!”

Lively, who is married to actor Ryan Reynolds, told the crew, “The cake is amazing, you do need to see that cake! You all need to see the cake.”
