It seems like Harry Styles is single again. Although the "Sign of the Times" hitmaker and his rumored girlfriend Tess Ward never confirmed their relationship, they pair are believed to have broken up after only a month of dating.

The Sun reported that the 27-year-old food blogger/chef recently rekindled her romance with her ex-boyfriend. "Tess realized she still had feelings for her ex after splitting from him to date Harry and has apologized to him for her romance with the singer," an insider told the website. "It will take a while for Tess to build back his trust but they have been getting on as normal."

The insider shared that Harry and Tess hadn't met each other for a long time. "Harry and Tess haven't seen each other for a number of weeks. They're both constantly traveling the world," the insider said. "She was in London this week and met her ex straight away - they've been inseparable since."

The two reportedly started dating last month after being introduced to each other by their mutual friends. "As soon as Harry met Tess there was an instant spark between them," a source revealed. "They really bonded over their mutual love of quirky fashion and food - and things turned romantic quickly."

Tess immediately became a target of jealous Directioners after the news broke. She later took to Instagram to clap back at haters. "Brunch for dinner is never a bad idea on the weekend!" she wrote alongside a photo of a delicious-looking meal. "Also for everyone following and messaging me, I am thankful but please be kind to me. All I want is to share beautiful food with you all."
