Looks like Brit got bad lip treatment while in Las Vegas.

The lawyers of Brit and Kevin will be in court tomorrow. Britney has some explaining to do about the light she blew that was caught on video and Kevin may have some explaining about his fast driving that was caught on film last night, with the boys in tow.

As far as the positive reading on the drug test... she tried the Provigil excuse, nope, that wouldn't show up in a drug test. Then the Albuterol excuse, nope, not an amphetamine.

Now... Adderall. It's an amphetamine, that's it! Adderall, we'll say she's got ADD and takes Adderall for it.

We'll see how that flies with the Judge.
