Dating rumors between One Direction's Harry Styles and former flame Paige Reifler spark once again, as they were recently seen flirting with each other.

The couple was first romantically linked last year, when photos of them getting cozy with one another were posted on Instagram. After dealing with online abuse from 1D fans for a while, the model eventually deleted her Twitter account while her relationship with the British pop star faded out.

However, it seems that Styles and Reifler may have rekindled their romance as they were spotted together getting cozy at the Warner Music & GQ Summer Party at Shoreditch House in London on Thursday, July 17.

"Harry turned up specifically to meet up with Paige but they were as discreet as possible at the event," a source revealed to The Sun. "They then both left the main party, which was on the rooftop next to the pool, and went downstairs to the more private restaurant. They were having drinks with her agents."

The "Midnight Memories" hitmaker apparently could not resist himself from getting intimate with the blonde beauty. "But Harry ended up putting his arm around Paige and they were very flirty together. They ended up leaving on their own because there were lots of photographers outside."

Meanwhile, Harry Styles now has some time to himself, as One Direction successfully wrapped their European tour just last week. The 20-year-old singer took to his Twitter account to thank everyone who has contributed to the shows: "Tonight is the last show of our European tour.. Thank you to all the crew who make the shows possible. You've been incredible. And to everyone who has come to the shows, you've made it so amazing so thank you for spending some time with us. You're incredible .xx."
