Yes that's Britney!
In relation to the last few conversations about potentially cody having a new gf and most likely introduced her to Arrow without Britneys knowledge; I I sole creeping and discovered Cody's new gf. He definitely is seeing someone else. Her instagram handle is: @wxaves
Well, he definitely has a type by the looks of it! She's just like a brunette version of Brittany, but more of a stuck in Tumblr from 10 years ago type of girl, which the same can be said about Cody.
If she really is his girlfriend, then I find it so odd how someone who's married and just had a baby can just move on this quickly. Can't imagine how gutted Brittany must be feeling, however, she does follow the girl on Instagram.
