As Naomi Campbell gears up to film the second season of her Oxygen reality show, “The Face,” in New York, we hear one of her first- season co-coaches and team rival Karolina Kurkova won’t be rejoining her. Sources tell us the Czech model and mother of a son, Tobin, 3, can’t be part of it because she has other work commitments. While Oxygen told us they and Campbell haven’t made any announcements about Season 2, a rep for Kurkova — who has appeared in magazine and ad campaigns for Roberto Cavalli and Net-a -Porter — told Page Six, “She appreciates everything the show did for her. She had a great experience and wishes them well.” “The Face” also stars photographer Nigel Barker as its host.
