Charlie Sheen and Denise Richards put their differences -- and Charlie's financial woes -- aside last weekend for the sake of the actor's 51st birthday. According to TMZ, Denise dropped off the couple's daughters, Sam and Lola, at their dad's private jet for a trip with his buddy Tony Todd to see two Macklemore shows. Seems the girls are hige fans, so Charlie took them to concerts in Seattle and Las Vegas.
