Why hello, single lady! Rita Ora stepped out just hours after Calvin Harris announced the couple had split at the Chateau Marmont in West Hollywood on Friday, June 6.

The British singer, 23, wowed during her night out in a cleavage-baring knee-length dress. She accessorized the sexy look with matching pumps and wore a bold red lip.

Harris, 30, took to Twitter earlier that day to set the record straight on the pair's relationship status. "To address speculation—myself and Rita ended our relationship some time ago," he wrote. "She is a beautiful, talented woman & I wish her all the best." Rita, who has yet to comment on the breakup, and the Scottish DJ first went public in May 2013.

Ora previously dated Robert Kardashian, blaming distance for their split in a December 2012 interview with Glamour UK. That same year, she had a brief fling with actor Jonah Hill.
