Blake Lively [1] has been busy promoting her newest movie A Simple Favour, and we couldn't help but notice just how much taller she is than her costar Anna Kendrick [2], who stands at 5'2". This isn't the first time Blake has towered over her fellow actors. Even back when she was Serena van der Woodsen on Gossip Girl [3], she seemed taller than fellow cast members including Leighton Meester [4], Ed Westwick [5], and Penn Badgley [6].

So just how tall is Blake Lively [7]? Well, we've got the answer for you: she's 5'10". This may make her much taller than many of her past and current costars, but she's still quite a bit shorter than her husband Ryan Reynolds [8], who is 6'2". While she often bridges the gap between her and her hubby's heights with sky-high Christian Louboutin stilettos [9], her killer high heel collection tends to make her tower over everyone else around her.
