Kim Kardashian and Kendra Wilkinson are ready to rumble!
The better halves to this Sunday's Superbowl stars had a pre-game radio chat Friday for KIIS-FM's On Air with Ryan Seacrest -- and weren't above a little faux-trash talk. Sniped Kardashian, 29, to fellow E! star Wilkinson, 24: "Let's meet up and I'll poison your coffee and you can give it to Hank!" (Kardashian's boyfriend Reggie Bush of the New Orleans Saints will play Wilkinson's husband Hank Baskett of the Indianapolis Colts in the eagerly-awaited match-up.)
Despite their rivalry, the pals told Ryan Seacrest they might pick up "celebratory lingerie" together. "Kendra, we should go shopping for it later today!" Kardashian suggested. "Text me!" Wilkinson replied.
Wilkinson's baby boy Hank Jr. flew in a plane for the first time for the big Miami game, and the new mom Tweeted before the flight that she was "sooo nervousssss!!!" She called in to Seacrest's show from the Colt's Miami hotel. "Hank comes in and spends time with the baby and has Daddy time with him," she explained.
The reality stars also dished on their all-important game-day outfits. Wilkinson will don "a jersey made that says 'Mrs. Baskett'." Hank Jr. "will be wearing [his father's] jersey." The new mom has made special accommodations for the baby: "We're going to sit in a box and well have headphones on him so he doesn't hear so much noise."
Kardashian, meanwhile, thinks wearing a jersey on game day is "superstitious," so will probably sport a "Balmain jacket, T-shirt and jeans and some boots...I always wear something in [Saints team colors] black and gold."
On game day, both sports gals "have our game day tradition where we hang out and have breakfast," Kardashian said. "All the players are on one floor...and the wives and girlfriends are on another floor. [The players] can come down for breakfast." Bush, 24, "makes a game day mix on his iPod."
"It's just another game, Ryan," Wilkinson added. "That's how you have to think of it."
Even Wilkinson couldn't resist asking Kardashian about the "engagement rumor." (Kardashian and Bush have both shot down talk that he would propose if he wins the game.) "What rumor?" she retorted. "I would want him to enjoy his moment if they win...like I would turn it around and be like 'now it's my time'? No...I want him to enjoy his time and that's totally a rumor."
So what if they get the victories they want? If her hubby wins, Wilkinson says she's already planned for someone to "hold the baby when I go on the field and am jumping around."
"I never say I hope the Saints will win," Kardashian said diplomatically. "They've put in hard work, they deserve to win."
