Just as soon as an excited Britney Spears announced her North American Tour, Billboard.com reported that Enrique had pulled out.

The tour was announced just before Britney's performance on GMA this morning. No official word has been given on why Enrique has pulled out but sources with Live Nation say the tour was set to feature a full production for both Enrique & Britney's performances.

Tour promoter Live Nation declined to comment but Billboard.biz will have more details as they emerge.
