I’m not a pushover and I’m not a hardass, but I definitely will defend myself if I need to.” When not attending weigh-ins, working fight nights or making public appearances (such as a meet and greet calendar signing at 9 on Vine in Los Angeles this Friday following the UFC 184 weigh-ins) in her capacity as Octagon Girl, Celeste works as a model and co-hosts “Overhaulin'” on Discovery Channel.
