I'll start with Sugababes' Keisha, who responded to a Britney question on Twitter:

 

Whats your favourite Britney Spears song?

" Sometimes and Born to make you happy lol Love Britney"

 

 

That was a reply to my tweet btw. :P

Kelly Clarkson loves her some Spears, she called Blackout some of her best work ever i believe.. I know she answered some questions about her... Her reaction to Britney shaving her head was PRICELESS :rofl:

 

Haha I love Kelly.

 

I know Madonna loves Britney's music. She said that Blackout was her favorite album to workout to back in 2008.

Loved when Kelly found out.

Keisha likes Born To Make You Happy, its my fave too :D
