Katy Perry co-wrote the new Selena Gomez track, “That’s More Like It.” Perry apparently wasn’t the only one who decided to lend a helping hand to the Disney star. Pop Princess Britney Spears co-penned the song, “Whiplash” for Gomez’s album. Now what did Gomez ever do to merit the support of two of the biggest names in the music industry? Anyway, Perry was recently seen sporting a new hair color which fans seem to be digging. The busy Mrs. Russell Brand released her newest single, “Thank God It’s Friday” earlier this month. Will “TGIF” be her first number one single from her album “Teenage Dream?” Perhaps the new hair color would help? We’ll see.
