Lisa Vanderpump is paying Kyle Richards no mind, exclusively revealing to Us Weekly what she thinks of her former Real Housewives of Beverly Hills costar using her own husband Ken Todd's iconic "Goodbye Kyle" line against him. "I don't really kind of invest in it too much, to be honest," Vanderpump, 65, told Us of the drama while promoting the upcoming Vanderpump Rules reboot. Confirming she and Todd, 80, did see Richards, 56, at the Beverly Hills Hotel ahead of BravoCon, Vanderpump said she didn't hear her ex-friend's diss.
