Katy Perry Poised to Make Music History
If her latest single, "Last Friday Night (T.G.I.F.)" can top the pop charts, Katy Perry will achieve something only one other artist ever has (and no female has).
Katy already has four No. 1 Billboard Hot 100 hits from Teenage Dream. Currently #4 and climbing, "Last Friday Night (T.G.I.F.)" would give her five.
