The reality star and Waits stepped out in late spring 2010, shortly after her final split from former "Hills" star Douglas Reinhardt. Explains the friend: "[Cy's] found it difficult to live his life with her in the spotlight and that's what caused their split. No drama, it's amicable, but things didn't work out."
