Be careful, or Blake Lively will surprise you with a baby

So maybe the real reason Blake Lively held off on announcing the birth of her daughter for a couple of weeks was so that she could punk her friends. She at least managed to pull off a surprise baby attack with one pal, “Sisterhood of the Traveling Pants” co-star Amber Tamblyn. When asked about how she found out about Lively’s big news, Tamblyn responds with a measured, “That bitch! She tricked me,” according to People magazine.

See, what happened was Tamblyn was heading up to Lively’s Bedford, New York, home recently totally unaware that the nursery was now occupied. “I went up there and I didn’t know. Everybody knew but me, and she does that s— to me,” Tamblyn explains. “She was texting me about wallpaper. She was like, ‘You’ve got to come see my new wallpaper.’ And I went up there, and there was her baby.” Enjoy it while you can, Blake, because that trick only works so many times.
