Supermodel Naomi Campbell and her ex-boyfriend billionaire Vladislav Doronin are allegedly locked in competing lawsuits over millions of dollars of belongings and gifts given to one another.

According to news reports, Campbell and Doronin dated for five years, ending the relationship in 2013. Campbell reportedly threw a three-day party in India for his 50th birthday, flying in Diana Ross via private jet to perform. Meanwhile, Doronin is said to have built her "a multi-million dollar love nest in a Moscow forest" and given her a 25-bedroom house in Turkey shaped like the Egyptian Eye of Horus as a 41st birthday present.

Campbell filed suit in London in February against Doronin, seeking to retrieve “some of her things...that are in his possession.”  In September, Doronin filed his own suit in New York Supreme Court against Campbell on grounds she never repaid a loan he gave her and she still is in possession of approximately $3 million of his belongings.

"She's been asking for these things back for years, but they've had no recent conversation. And then he went and did this," said an unnamed source.

Though her rep had no comment, a friend of the two told news sources the legal back-and-forth "can't be just about the cash," given his billionaire status and her estimated $80 million net worth. "It's about the game. It's a power thing," the friend surmised.

Reportedly, Campbell and Doronin eventually split after he was caught "passionately embracing" a Chinese model in Ibiza. The model, Luo Zilin, was someone Naomi had previously mentored, according to the news sources.
