Billie Piper has said she can't ''remember a lot'' of her early fame after first topping the charts as a teenager.
The 37-year-old singer, who reached No.1 on the UK charts at the age of 15 with her catchy track Because We Want To, admitted she "buried" a "lot of stress" from that time in her life.
Speaking to Radio Times magazine, she said: ''I'm sure it feeds into my performance. I'm only coming to terms with a lot of it right now.
''In my 20s a lot of my stress from that period was buried, and I still struggle to remember a lot of it."

The chart-topper who has sons Winston, 11, and Eugene, eight, with ex-husband Laurence Fox, said she doesn't ''regret'' her early career, but insists she wouldn't want her children to take the same path.
''I love what I do and where I'm at personally. But I certainly wouldn't want my children to go that way," she added.
