L.A. diners are used to seeing old dudes sitting beside their barely legals while matrons scan dens like James Beach for a surf-stud to take home. But what do you call a 17-year-old cougar? We're not sure there's a term for that yet, so let's just start calling it a "Cyrus" after young Miley. The Disney actress caused quite a hullabaloo when she brought baby-faced Justin Bieber out for a sushi date at Ari-Ya, breaking many a pre-teen heart along the way. We'll update you if it leads to a fight with Bieber's other older woman, Kim Kardashian, or if we spot Miley hovering too closely to any area junior-highs. Speaking of
kiddie kitty fights, Avril Lavigne screamed out from the void, yelling at Lindsay Lohan this week at Chateau Marmont for something that was no doubt pretty important. Showing rare good judgment, Lohan stormed out of the club herself before security could give her the Trousdale treatment. While we ponder that bumpy road that leads to maturity, check out where else celebrities have been dining this week in L.A.
