Britney Spears flaunted her curves in a tight black tank top and black pants for lunch with her boyfriend, David Lucado, at The Napa Tavern in LA yesterday. Britney has been dedicated to writing her new album lately, and she has been documenting the process on her Twitter account, revealing one of her new collaborations earlier this month, writing, "Had an amazing writing session today with the beautiful and talented Sia. We wrote such a special song together." Britney gave a glimpse as to what her latest album may hold with her single "Ooh La La," which was featured on the Smurfs 2 soundtrack. Two weeks ago, she released the video for "Ooh La La," which was a special one for Britney since her boys, Jayden James and Sean Preston, made their debut in the kid-friendly music video for the single.
