....It's Bottle Pop.
It follows #9 hit "When I grow Up" and the latest digital release, "Whatcha think about that" and 2nd worldwide single "I Hate this Part", which is currently making it's impact all over Europe. Bottle Pop already features on the widget on their official site and on Facebook-application, also being reported on various of music sites.
They really need to catch a hit with this after the dissapointing album sales. The Dolls only sold around 75k on their first week of release in the USA. Personally I think Halo would have been a better choice.
Listen 'Bottle Pop'
Halo (My preferred choice for 3rd single)
