Kim Kardashian and Reggie Bush

says it was like looking in the mirror when she watched her friend, Girls Next Door
star Holly Madison, debut on Dancing With the Stars
“Holly reminded me of me out there dancing – only she did a better job,” Kardashian, 28, told PEOPLE while sitting atop boyfriend
Reggie Bush's lap at the Fontainebleau Resort in Miami Beach Saturday night. A Dancing
alum, Kardashian competed on the show
with partner Mark Ballas last fall.
“[Holly] looked nervous like I was while dancing on the show," Kardashian said. "She is such a sweet person with a fun personality. I am really excited for her, and I want her to do well.”
Kardashian was the Fountainebleau to host the Russell Simmons and Rush Philanthropic Art For Life benefit. Meanwhile, her own reality show, Keeping Up with the Kardashians
, keeps Bush, 24, a running back with the New Orleans Saints, laughing at the family antics. He especially gets a kick out of the bickering among Kim, her sisters Kourtney and Khloe, and their mom Kris Jenner.
And most important, Bush is very supportive of his girlfriend and her smokin' hot career. “Kim is great on the show, and on top of that she has a wonderful personality because she is down to earth, caring and approachable,” Bush tells PEOPLE. “Even though we come from different worlds – she's a Hollywood kid, and I am a sports guy – we like many of the same things – eating, watching movies and outdoor activities. I am happy for all of her success.”
