The relationship between Koepka and Sims was fairly unknown before the major championship in Wisconsin.
The only problem? Koepka and Edwards are no longer dating.
Her Wikipedia page contained an update Sunday night that described her as Koepka's "new" girlfriend.
There was a slightly awkward moment for those watching on TV as FOX's Joe Buck incorrectly identified Koepka's girlfriend as Becky Edwards, a pro soccer player. But the woman celebrating with the new U.S. Open champ was actually Sims, an actress and former beauty pageant victor.
Jenna Sims did not comment on the mishap but she did share a photo of herself and Koepka shortly after he won the U.S Title.
