Sorry, Kyle Howard: LC's got a new man!

Lauren Conrad and Dancing with the Stars pro Derek Hough have gone public with their romance! An insider tells the new Us Weekly -- on stands Friday -- that the reality stars have seen each other "a few times" since their first date in September.

Conrad, 25, and Hough, 26, headed to L.A.'s Sayers Club on Sept. 29. "They were very flirty," an eyewitness tells Us. "They were dancing and holding hands!"

A friend of Conrad's tells Us that the designer -- who split from Howard, 33, in June -- might be ready for a new long-term love. "It hasn't been easy moving on, but Derek has been sweet," says a friend. "They are having fun and seeing where it goes."
