La Toya Jackson, Brooke Mueller, Kyle Richards and Nicky Hilton got together to celebrate Kathy Hilton's birthday at Il Cielo in Beverly Hills yesterday, and despite the gloomy weather, the ladies appeared to have a great time catching up.

Kathy already celebrated her 53rd bday at Mr. Chow and Dan Tana's earlier this week, and we're guessing the party is going to keep on going throughout the weekend!
