"I guess that Bieber Fever really got to people," Kim's sister Kylie Jenner,11, joked with us Saturday at 102.7 KIIS-FM's Wango Tango concert in L.A.
Was Kim threatened at all by the haters?
"No!" Kylie assured us. "Not at all."
So what is going on with Kim's love life these days? Kylie and Kendall filled us in...
"She's just not looking for anybody right now," said Kendall,14. "She's just so busy. She's just playing attention to her work more than a guy."
However, Kylie said she wouldn't mind if Kim got back together with Reggie Bush. "They're a good couple," she said. "They're both really nice people."
Speaking of romance, our E! News buddy Ryan Seacrest joked with reporters that he knows what he's getting Simon Cowell for a wedding gift—at least we think he was joking. "He loves teddy bears," he cracked. "He's got stuffed animals on his bed so I might get him a Care Bear."
And if that doesn't work out, Seacrest cracked, "I'm thinking a statue or sculpture of me that he can put in his courtyard with running water around it."
Also at Wango Tango were Bieber, Adam Lambert, Ludacris, Usher, Twilight's Ashley Greene and a gaggle of Hills stars like Brody Jenner, Kristin Cavallari and Stephanie Pratt. Ke$ha was her usual bizarre self, carrying around a dollhead that she referred to as "Brian the Brain."
No word on where the rest of the doll's body is.
