Was the Pixie Lott song "Mama Do" ever the #1 single?

"Mama Do" debuted at #1 on the UK Singles Chart in its first week and also was successful outside the UK, appearing in the Top 10 in Denmark and France and the Top 20 in Ireland, the Netherlands, and New Zealand. The British Phonographic Industry certified it as Silver the same year it was released and upgraded the certification to Gold eleven years later.
