Speaking on the Radio 1 Breakfast show to presenter, Chris Moyles, the singer told fans to "watch out" for upcoming projects.
She said it's been almost three years since the five girls, who have said in the past they will get back together when the time is right, announced a temporary split and are ready to reunite:
"It's coming up to our 10th birthday in November this year... and we all want to do something to celebrate that,"
Girls Aloud took a break in 2009 and Cheryl has gone on to have a solo career with number one solo singles with Fight for This Love and Promise This.
Discussing the split, she said: "What happened was it had been seven years of consistently non-stop touring, album after album.
"As women we needed this space to grow."
The 28-year-old former X Factor judge appeared on Radio 1's Breakfast Show to discuss her new single Call My Name. Her next solo album is due out later this year.
