Sienna Miller and Balthazar Getty are still going at it.
Despite leading the world to think their relationship is over, RadarOnline.com has exclusively learned the 2 have been canoodling in private at a West Hollywood hotel.
"They spent Sunday night together in her suite," an insider reveals. "She's staying under another name."
27-year old Miller made international headlines last summer when she and very married Getty were intimately photographed on vacation together.
Miller (Jude Law's former wife) has been romantically linked to the 34 year-old "Brothers and Sisters" star since May, around the time Getty's wife, Rosetta Millington, was popping out kid number 4.
Getty claims to be "legally separated."
