The pop five-piece are currently on hiatus, having last performed together at Wembley Stadium in September 2009, where they supported Coldplay. Walsh, along with other members of the group, have said they hope to reunite to celebrate their 10th anniversary next year.
"We all definitely want to do something to celebrate our 10-year anniversary because it's a massive achievement," she told The Mirror. "There aren't any actual plans in place - if there were we wouldn't be telling you! We definitely do want to do something. We will definitely regroup."
Teasing what could become of the 'Something Kinda Ooh' group after their reunion, Walsh added: "I don't think that will be the end, though. I don't think we will ever break up. Girls last forever."
Nadine Coyle recently confirmed that a reunion would "definitely" take place, adding that the girls "always discuss doing a 10-year reunion thing".
Walsh will take over Amanda Holden's role as Princess Fiona in Shrek: The Musical. The 29-year-old will make her West End debut in October.
