Erin Walker is the wife of PGA Tour player Jimmy Walker. And yes, this photo is from the PGA Tour wives shoot recently done by the studio Reverb Collective.
When these images were first posted on Golf.com, that site implied that all the women featured were angling for a reality TV series. But actually, only a couple of them are. Erin Walker has made clear on Twitter that she has no interest in a television series. "Inside The PGA Tour is the only show the hubby and I will be doing. Reality or not," she tweeted.
