New Jonas Brothers news!

The Jonas Brothers are not having a good week ... and it is only Wednesday. Their concert film ' "The Jonas Brothers: The 3D Experience" ' was a big box-office disappointment, earning only $12.7 million last weekend. Expectations had been as high as a $40-million opening for this movie version of the recent sell-out tour by the Jonas Brothers. And now comes word that the soundtrack sold only 49,700 copies last week.

Worse, their newest music release came in at No. 3 ' that's two slots behind "Fearless," the latest mega-selling CD by Joe Jonas' ex-galpal Taylor Swift. "Fearless" had already topped the charts for 10 previous weeks, so the fact that Joe Jonas and siblings couldn't dislodge it at this late point with fresh new music is sweet revenge for Swift, who says Joe hurt her "deeply" during their failed romance.

How much more humbling can those way-too-cool Jonas Brothers take, eh? Their latest CD is performing disastrously compared to their last ' "A Little Bit Longer" ' which debuted at No. 1 in August, selling a whopping 525,000 copies. The recent anemic movie and record receipts came after a huge promotional push that saw the boys blanket day-time, prime-time and late-night TV shows.

Last year the Jonas Brothers were the opening act for Miley Cyrus on her Best of Both Worlds tour. They also appeared in the movie version of that show, which made a staggering $31 million in its opening weekend last year. And the soundtrack to that film sold a total of 484,000 copies.

Miley Cyrus does not appear with the Jonas Brothers in their movie, but her friend Taylor Swift does duet with the boys. The crossover country singer is enjoying a long run at the top of the album chart with "Fearless" selling 73,200 more copies this week. And Swift's disc has spent 11 of its 16 weeks in the No. 1 spot with total sales exceeding 2.6 million. Perhaps Disney would have had better luck starring Swift in a concert movie and leaving the Jonas Brothers second on the bill.

After the smash success of her self-titled debut album, which sold more than 2.5 million copies following its release in October 2006, Swift competed for best new artist at last year's Grammy Awards. She lost to British singer-songwriter Amy Winehouse. At this year's Grammys, the Jonas Brothers lost their bid for best new artist to another British female singer-songwriter, Adele. The nominees for that category are determined by a committee rather than the general membership of the Recording Academy. And though both Swift and the Jonas Brothers may have been included in an attempt to boost ratings, she could well be a contender across the board next year.

Taylor Swift has been embraced by the two rival country music award shows. She won best new artist from both the Country Music Assn. and the Academy of Country Music. And she contends for the third time for female vocalist at the upcoming ACM awards. And as for the Jonas Brothers, well they did win favorite group at last year's Kids' Choice Awards, and they contend again for that honor at the end of this month.
