Are Big Time Rush Getting Torn Apart by the Ladies?

The band Big Time Rush (who got their start as a group on a Nickelodeon sitcom) say they're still going strong and not on the way to a breakup even though their show is off the air, but all their promises reportedly may come to naught if Carlos Pena's fiance/actress Alex Vega has her way.

Sources close to the band talked to TMZ about the issue, saying that band members Kendall and Logan are of the firm belief that the group is having girl-related troubles which could bring about their downfall.

Specifically, Vega wants Pena to spend more time with her working on wedding planning and less time with the band, which would make it hard to tour.

One of the band's other members, James, is suffering similar problems -- supposedly, his girlfriend says they should be spending more time together as they're in a "committed relationship."
