You would think that selling ten million albums would afford you a bit of breathing room.

However, a little over a year after delivering her debut smash "...Baby One More Time," Britney Spears is feeling the pressure of following up that album's huge commercial success.

"It's kind of hard following ten million, I have to say," Spears told MTV News when her tour rolled into Chicago recently. "But after listening to the new material and recording it, I'm really confident with it."

That new material will surface on May 16 on "Oops!... I Did It Again," an album Spears recorded in Sweden and Switzerland with producers Max Martin and "Mutt" Lange (see "Britney Spears Works On Next LP In Switzerland, Sweden").

Glimpses of the new album have come with Britney's new video for the album's title track, as well as her recently completed Spring tour. Spears had been rolling out "Oops!..." in her set, as well as a new song called "Don't Let Me Be The Last To Know," a ballad that saw Britney perform atop a flying carpet.

"That was awesome," one fan gushed of Spears' high-flying act. "It was like 'Genie In A Bottle,' Britney on a rug."

Spears wrapped up her tour last weekend in Charleston, West Virginia, and now plans to return to the road on June 15 for a summer tour in support of "Oops!..."

"I can't wait. I'll have a world tour," Spears said. "I'm going to have more dancers, a bigger stage, more pyro… just a lot bigger." [RealVideo]
