Britney Spears Wishes Janet Jackson "Happy Birthday"

Singer says she's been a fan for as long as she can remember

Happy birthday, Janet Jackson!

Ms. Jackson has a super fan in one of the music industry's most famous faces: Britney Spears.

The pop princess tweeted to the "Escapade" singer in honor of her special day.

Spears wrote, "Happy happy birthday to @JanetJackson!! I've been part of the #RhythmNation for as long as I can remember!!"

We imagine the message was well-received by the singing icon, who we bet was flattered by the news of Spears' ongoing support.

Now if only these two could collaborate on new music together!
