Jimmy Choo president Tamara Mellon and socialite Kimberly Stewart have embarked on a war of words after the shoe designer found out her boyfriend had been photographed kissing Rod Stewart's daughter.

Mellon and GIRLS GONE WILD producer JOE FRANCIS have been dating for several months and were planning to spend a romantic few days in Francis' Mexico compound last month (AUG05).

However, days before Mellon was due to board Francis' private jet to his hideaway, she discovered Francis and Stewart had been acting affectionate at the taping of Pamela Anderson's COMEDY CENTRAL roast - the same night he was due to have dinner with Mellon.

After a fuming Mellon called Francis to confirm she was flying to Mexico with him, she sent a messenger with photos of him and Stewart to 'meet' him at the airport instead, reports PageSix.com.

A representative for Jimmy Choo says, "Apparently his jaw dropped, because she had acted on the phone as if nothing was wrong. I don't know why he thought no one would notice him with Kimberly."

Francis, who admits dating both women but denies he was jilted at the airport, responds, "Tamara is just f**ked off because she was embarrassed that PageSix reported she crashed Kim's birthday party. She came up and threatened us at a party. It's constant bickering back and forth between those two girls, and it needs to stop. I tried to get them together to talk out their differences."

Aspiring actress Stewart fires back, "There are so many more interesting things in the world than f**king Jimmy Choo. Maybe (Mellon) is just upset that I pulled up in Francis' Ferrari at Le Soleil."
