Mariah slays with her #1s

I Kissed a Girl
California Gurls
E.T.

I Kissed a Girl (7 weeks)
California Gurls (6 weeks)
E.T. (5 weeks)

So many weeks!!!

Queen of Pop Rihanna has 5:

Umbrella
Live Your Life
Rude Boy
Love The Way You Lie
We Found Love

Six.

That record.

Gaga:
Born This Way - 6 weeks

The one I was looking for was for Britney Spears but I couldn't find anything on hers.

Only 1 which is the timeless masterpiece, Take A Bow.

"I'm Real" [Murder Remix] - 5 weeks
"Ain't It Funny" [Murder Remix] - 6 weeks



Edit: My mistake AIF spent 6 weeks at #1.

Born This Way: 6 weeks.

Lose Yourself (12 weeks)
Love The Way You Lie (7 weeks)

"Born This Way" for six, "Like a Virgin" for six, "Take a Bow" for seven. Britney has none that have reigned that long in the US; before 2008 she was always more of an albums girl.

I found Bey's info. on this thread.
