Kim Kardashian's Wedding Wishes for Kendra

But that doesn't make Kardashian any more anxious to walk down the aisle with her own NFL-star beau, the New Orleans Saints' Reggie Bush.
"I am so excited for Kendra," Kardashian, 28, tells PEOPLE of the Girls Next Door star. "It's good to see her happy. But this doesn't change my feelings for Reggie or our relationship at all. It is good now, and I just let it flow."
Kardashian – looking stunning in a long brown off- the-shoulder gown and diamond earrings – was in Miami for the annual gala thrown by the Make-A-Wish Foundation of Southern Florida.
But she planned to jet out shortly after the event. "I am flying to New Orleans to help Reggie rehab from a football injury in hopes he can play in next week's game," she said. "I will be there with him all week."
In addition to filming the new season of E!'s Keeping Up with the Kardashians, the reality TV star is also rehearsing for the grand finale of Dancing with the Stars.
"I absolutely loved doing the show [earlier this season] and wish I was still on," she admitted. "It was hard work but I was really into it. And I made so many friends there! I am excited about going back."
