Nicole Scherzinger may have left The Pussycat Dolls a year ago, but it looks like there is still some beef with the group's founder, Robin Antin.
According to an insider, "On July 6, Kim Kardashian was celebrating Robin's birthday with her at Soho House New York, and Nicole was sitting two tables away from them."
The insider adds that Robin and Kim did not acknowledge Nicole, and the new X-Factor judge did not pay attention to her former boss, either.
Another insider tells In Touch exclusively, "Robin has moved on. She has already cast her new lineup of The Pussycat Dolls and they are launching in December."
