That's Heidi with an H.

That's Heidi with an H.

The artist formerly known as Heidi Montag and who is now—legally at least, Heidi Pratt—tells E! News exclusively that she wants to join the nomenclature ranks of other female celeb superstars.

"In keeping with the great tradition of stars like Madonna and Cher who are on a first-name-only basis with their fans, I've decided to go by the name of 'Heidi,' " she says.

Husband Spencer Pratt tells E! News that he fully supports her decision.

"Legally, she's a Pratt. But to her fans she is 'Heidi.' I totally support my beautiful wife—no matter what she calls herself."

But Spencer tells E! News that, for the moment, Heidi, as recently announced, is going to go by the stage name "H" as a recording artist.
