The 24-year-old star was reported to have said 'I do' to her bearded partner after she was spotted wearing a gold band ring on her wedding finger back in July.
However, the British singer took to twitter to inform her 9,094,078 followers that the reports were not true.
"I'm not married...Zzzzzz," Adele wrote.
Simon already has a daughter from his first marriage to Clary Fisher in 2004.
The Grammy-winning singer was introduced to Simon by singer Ed Sheeran during a difficult period, when she was recovering from surgery on her vocal cords.
