There’s something very interesting about the photos from Kim Kardashian’s 30th birthday party — Perez Hilton is there. Perez Hilton has often bashed the Kardashian sisters on his blog, once going so far as to call Khloe Kardashian an “ugly amazon.” So does she have a forgiving heart, or is she hoping to stay close to Perez to keep her name on his website? I surmise it’s the latter. And the Kardashians aren’t alone. Demi Moore once threatened to sue Perez for child pornography when he posted pictures of her young daughter’s ass on his website. Perez then countered with a defamation threat. You wouldn’t guess that by the twitter love between the two. Demi posted a twit-pic of herself in a bikini, and Perez responded with a pic of himself a speedo. Demi playfully retweeted his pic, saying, “I think I started a trend.” Did she forgive him too? And what about Lindsay Lohan? Perez often attacks her on his site, yet Lohan had no problem attending his birthday bash, and getting her picture taken with him. Nothing says forgiveness like getting your name mentioned on a high-traffic blog.
