Bret Michaels is keeping up with Kim Kardashian.

The Poison singer -- who survived three major health scares last year -- got personal with the 30-year-old E! reality star when she climbed aboard his tour bus late last month.

"She was like, 'Oh, this is beautiful. Nice bus,'" Michaels, 48, tells "We talked about how she was doing. We talked a little bit about my health. Talked about the concert. It was very cool. She was very, very polite. I mean that. Very sexy, very cool, very together."

After their 10-minute encounter on March 21, Michaels tells Us he's smitten with Kardashian, who introduced the Life As I Know It star at his charity concert in Orlando.

"I admire her beauty. She's got one of the prettiest faces ever," he fawns. "Sometimes you see someone, and then you see them in person and it's not quite the same. She was very beautiful in person."
