Christina Aguilera to tour as Baby Jane

All grown up and with a new jazz- and blues-inflected double album on the way, Christina Aguilera plans to do a US club tour under the name Baby Jane. The moniker appears as the license plate of the car Aguilera emerges from at the outset of the video for "Ain't No Other Man," the first single off the upcoming Back to Basics double album.

Aguilera told MTV News that the as-yet-unnamed concert venues where she'll perform will reflect the tone of the new album, which takes a retro look at the soul, jazz, and blues from the 1920s, '30s, and '40s. "We're gonna' go around to small little jazz and blues clubs around the country, which is the setting and tone of what this album is really inspired by," she said. (12:30 p.m.)

Former Britney guards must seek arbitration

If three former security guards for Britney Spears want to seek back pay they claim the pop star owes them, they must do so through arbitration and not the court system, a judge ruled yesterday.

Silas Dukes, Lonnie DeShawn Jones, and Randy Jones sued Spears in March, saying two of her companies failed to pay them overtime wages to provide security for the 24-year-old pop star and her home at $2,400 to $3,350 per week. But a judge ruled that the original agreement between the parties called for wage disputes to be arbitrated. (12:00 p.m.)

Notorious BIG retrial delayed further

A federal judge has postponed until January the long-delayed retrial in the wrongful death lawsuit brought by the family of slain rapper Notorious BIG against the City of Los Angeles. The case centers on the potential involvement of two ex-Los Angeles police officers in BIG's murder on an LA street in March 1997. US District Judge Florence-Marie Cooper declared the case a mistrial in the original lawsuit last September, saying that a police detective had intentionally concealed key documents. Cooper had set a retrial date for October but delayed it until January to give the family's attorneys more time to seek information from the defense. (11:40 p.m.)

Arctic Monkeys bassist to leave band

Arctic Monkeys bassist Andy Nicholson's "fatigue" was enough to make him rethink being in the band altogether. Nicholson, who founded the UK buzz band with longtime friends Alex Turner, Jamie Cook, and Matt Helders, has left the band permanently after taking a touring hiatus due to "fatigue," according to a statement on the band's Web site. "We are sad to tell everyone that Andy is no longer with the band," they wrote. "Nick O'Malley, who stood in for Andy while he was absent from the recent tour of North America, shall carry on playing bass for the remaining shows this summer. We have been mates with Andy for a long time and have been through some amazing things together that no one can take away. We all wish Andy the very best." (10:30 p.m.)

Warner Music inks Chinese wireless deal

Warner Music Group (WMG) has signed a deal with China Unicom, allowing the label giant to sell ringtones and voice greetings to the Chinese wireless provider's customers without going through a third party. China Unicom is the nation's second-largest mobile operator with 133.9 million subscribers. Although WMG's artist roster includes the likes of Madonna, Green Day, and Sean Paul, the deal will focus largely on popular Asian artists like Stephanie Sun, Tanya Chua, Wang Jing, and Paul Wong.

The deal is the latest in a string of worldwide agreements WMG has inked to distribute its music to mobile phone users. In May, the company struck a deal with South Korea's top wireless operator, SK Telecom, and another deal with South Africa's Johnnic Communications. (9:45 p.m.)
