But above many other reasons, the E! reality starlet is excited about being closer to her ex-boyfriend Hugh Hefner.
"I can tell you that Hef is my closest friend," Wilkinson, 25, told PEOPLE. "I'm not just saying that. He makes sure he writes to us every chance . . . He's always thinking about us, and that's a real friend."
But it doesn't sound like hubby Hank Baskett has any reason to be concerned.
"I want Hef to see how my life is – it's just great," Wilkinson said, gushing about Baskett and their 10-month-old son. "I'm just excited to catch up on things."
Wilkinson, who caught up with her long lost pal Thursday, calls Hefner a very thoughtful man. "Hef always says, 'I'm thinking about you,'" she said. "He asks, 'How are you guys doing? Are you doing okay?' "
The former Girls Next Door star makes no mention of her previous Playboy Mansion roommates Holly Madison and Bridget Marquardt, emphasizing that Hefner is the one who called with concern when Baskett was cut from the Philadelphia Eagles.
"Hef is so happy to see us," Wilkinson says. "And we're so excited to see him."
