Britney Spears is whipping herself into shape for her new music video -- starting with her hair!
The singer was spotted going into the dance studio yesterday with some brand new hair extensions, looking a lot better than the last time we saw her go in for a studio session.
Spears, who is currently training for the "Hold It Against Me" shoot, tweeted yesterday "Dance, dance, and more dance. Getting ready to shoot the video for HIAM this week with Jonas Akerlund. Super excited!"
Akerlund also directed the "Telephone" music video for Lady Gaga and "Beautiful" for Christina Aguilera.
After rehearsals, Brit's manager Adam Leber also tweeted "Amazing day in the studio today. You guys should be very excited. This album is going to be incredible. Dare I say the best yet?"
