*Bad news for Maxwell fans hoping to see him on the second part of his summer tour – you’ll have to wait until next year.

The singer has announced he is pulling out of his U.S. tour with Jill Scott and Erykah Badu citing “scheduling conflicts.”

According to his camp, Maxwell will play all of his dates up to and including sold out concerts at New York’s Madison Square Garden on June 25 and 26, but he has postponed the entire second leg of the trek.

He was due to perform 11 shows between June 28 and July 15, in such cities as Nashville, Tennessee and Boston, but the gigs will now take place sometime in 2011.

Now for the drama: There are rumors that Maxwell’s so-called “scheduling conflicts” is really a cover for a major disagreement he’s supposedly having with Jill Scott and Erykah Badu over time slots in the lineup.

Scott’s publicist has already slammed the reports, telling Billboard.com, “Jill has enjoyed every moment on stage with Maxwell, whom she calls a consummate gentleman and tour mate. She looks forward to sharing the rest of the tour with all of the supportive followers.”

And Maxwell’s reps at Shore Fire Media just continue to blame the cancellation on “scheduling difficulties” without going into further detail.

The publicity firm also stated: “Due to scheduling conflicts with the venues, Maxwell’s additional tour dates with Melanie Fiona (scheduled to begin June 28 in Greensboro, N.C.) have been postponed to 2011. Refunds have been provided to ticket buyers. New dates will be announced later this year.”
