Did Harry Styles' Rumored Girlfriend Do Something 'Sickening' To An Ex?

On Tuesday, Mirror reported that X Factor host Caroline Flack, who apparently used to date Styles, flirted with One Direction member Niall Horan at the Dorchester hotel bar. These two supposedly had some giggles when Flack was heard telling Horan, "I'm old enough to be your mother."

As the night continued, these two seemed to have a blast together. The night had to come to an end at some point though.

"It was a fun night and these two looked [like they] were the life and soul of the party, Cazza even looked disappointed at the end when he left to head off to a club," a source said. "She was hugging him tightly and kissing him on the cheek."

Flack wrote an autobiography about what she dealt with when she had her apparent romance with Styles. When this got out to the public, the woman's life took a rough turn when people saw her.

"It began to go wrong when Harry was pictured coming out of my house one morning. And once that was out, it was open season," Flack wrote via People. "After that anyone could say anything. In the street people started shouting at me 'pedophile' and 'pervert.'"

This also led to nasty threats on social media from One Direction fans.
