Thankfully, Chrissy Teigen is already super famous, because if she were to ever compete on America's Next Top Model and get to the commercial challenge, Tyra Banks [1] would send her packing. At least that's what it looks like in bloopers from the Lip Sync Battle cohost [2]'s new commercial for hair care brand TRESemmé (of which she's now the spokeswoman for the Beauty-Full Volume line [3]), since she can barely get through a take without unleashing her truly infectious giggle. From cuddling with her bulldog Puddy to goofing off in a photo booth with her costar, Chrissy is every bit as candid and hilarious as she seems [4]. Watch the video above, and then check out her most adorable baby bump snaps [5]!
