The 'Someone Like You' singer, who collected six Grammys at the weekend, told fans that she will be recording new material shortly after her appearance at the Brit Awards on February 21.
"I've a few days off now, and then it's the Brit Awards here at home and then I'm straight into the studio," Adele wrote on her official blog. "BOYYAHH! 5 years? More like 5 days!"
Adele also opened up about her triumph at the Grammy Awards, describing Sunday's (February 12) ceremony as the "most incredible night of [her] life".
"Oh goodness! I'm absolutely flabbergasted," she continued. "I keep having flashbacks to Sunday night. The most incredible night of my life. Thank you to you all, I am so overwhelmed, it's the strangest feeling. I have constant butterflies and goosebumps, it's wearing me out but I LOVE it!"
Adele apologised for forgetting to thank several important people when collecting her awards, explaining that she was "totally unprepared" to win.
"Despite the phenomenal year, I swear I didn't think I had any chance," she said. "All the categories were full of people I adore with brilliant songs, records and performances. So not in my wildest dreams did I think to actually prepare anything proper to say just in case."
Adele recently described her recovery from throat surgery as a "really peaceful" time.
