Paris Hilton and Cy Waits: It's over

paris-hilton-cy-waits-getty.jpgAfter a year of couplehood, Paris Hilton and boyfriend Cy Waits have split.

"They are broken up," a source tells Us Weekly. "It's sad, she cares about him a lot and thinks he's a great guy but they really hit a rough patch."

Hilton and the Las Vegas nightclub owner started dating in spring 2010 soon after Hilton broke up with then-boyfriend Douglas Reinhardt.

"[Cy's] found it difficult to live his life with her in the spotlight and that's what caused their split," the source continued to Us. "No drama, it's amicable, but things didn't work out."

At an April court appearance, Waits was with Hilton when the reality star was accosted by an overzealous fan outside a Los Angeles courtroom.
