LAUREN Conrad has split from her boyfriend. The former Hills star and actor Kyle Howard have ended their three-year relationship, though the reasons behind their separation have not been made public. It seems Lauren has turned to nature in order to keep busy following her split. Second day in a row I have almost stepped on a snake while hiking, she wrote on Twitter. Despite living her life in front of the cameras, Lauren, 25, managed to keep her relationship with the 33-year-old hunk largely out of the spotlight. By the time I had met Kyle, I had already perfected my 'double life. There was my TV life and my real life, she said earlier this year. SS
