Jennifer Lopez performed on Dancing with the Stars last night, singing her latest single "Do It Well" and her classic "Let's Get Loud."

She also wore broad, baggy tops to cover up the fact that SHE'S PREGNANT.

While we're happy for Ben Affleck's ex and Marc Anthony's current, we're bothered by her baby bump secrecy because it seems like an attempt to remain in the celebrity gossip spotlight, in light of the fact that J Lo's career hit a recent low when her new album Brave sold just 53,000 copies in its first week.

At least this should leave Lopez with more time to spend with the upcoming child. Maybe she'll be able to avoid the pitfalls of famous mothers such as Lynne Spears.

In Dancing with the Stars news, Mark Cuban was voted out last night. We love him, but it was definitely time to go.
