Blake Lively's 30th birthday celebration was so great, you could almost say it was "pitch perfect." On Sunday, the actress celebrated her big day by going out to dinner with a few of her friends, including her A Simple Favor costar Anna Kendrick. "My super sweet 16 . . . but like 14 years late," she captioned a photo of her sitting next to Anna at the table. Looks like these leading ladies are getting closer as they film their new movie! She also snapped a selfie with jewelry designers Lorraine Schwartz and Ofira Sandberg, who shared a photo of Blake with her sparkler candles during the party. The actress also gave a hilarious warning to her friends who weren't able to attend and celebrate: "You're dead to me." While Ryan Reynolds wasn't in the picture, he did make a point to wish his wife a "happy birthday" on Instagram with a hilarious post.
