Enjoying a swanky evening out, Kim Kardashian was spotted hitting up the celebrity-popular restaurant Katsuya last night.Meeting up with sister Kourtney and her babydaddy Scott Disick, the “Keeping Up with the Kardashians” babe looked lovely as she strolled past the paparazzi, happily tweeting "Sushiiiiiiiiii".

In related news, Kim’s ex-boyfriend Reggie Bush was apparently deterred from marrying her because of his mother’s wishes.An inside source explained, “His mother does not want her son dating someone who has a sex tape out there. He is such a mamma’s boy; he will never marry her because she would disown him. He respects his mother’s opinion and would take that into account before even his own feelings, so he will never marry Kim.”
