Naomi Campbell was unfazed when she bumped into ex-boyfriend Vladimir Doronin while partying in Ibiza. The 42-year-old supermodel had a nasty split from the billionaire, who moved on to Campbell’s protégé Luo Zilin, 25, in June.

Zilin was on Campbell’s “Team Naomi” on the modeling competition show "The Face" earlier this year, becoming a runner-up, thanks to Campbell's mentoring.

At club Ushuaia on Sunday night, Campbell was celebrating her latest magazine cover for Interview, in which she poses nude. She was with fashion photographers Mert Alas and Marcus Piggot, as well as Maxwell and Paris Hilton. Doronin sat behind the group of celebrities.

“The atmosphere was icy. They didn’t speak even though they were at a table right next to one another,” a source told the New York Post’s Page Six.

After Zilin and Doronin publicized their relationship, the supermodel reportedly tried to get the 25-year-old model fired by her Chinese modeling agent.

The aspiring model was fired shortly after from her management company. Neal Hamil, president of MIX Model Management NYC, blamed Zilin’s lack of work ethic for her getting canned, but it is suspected that Campbell had some input as well.

“Naomi has been calling colleagues in the industry to try and stop Luo’s career. She is trying to take this woman out for no reason other than dating her ex-boyfriend,” a source tells New York Post’s Page Six.

“Naomi is trying to wreck her career. She has a lot of power in the modeling world,” the insider continued.

It was reported in the beginning of May that the British supermodel and Doronin were taking a break after being together for five years. Campbell has since been busy with her hit reality show and photo shoots. She is expected to return to New York next month to shoot season 2 of “The Face.”
