Heard the one about Britney Spears getting collagen lip injections and then driving over a photographer? There’s no actual punchline, because Britney’s enough of a joke on her own. As you can see in the above video, the wreck of a singer left an LA medical center covering her mouth. Pics show her lips looking extra large, but maybe they’re just swollen from eating too many Big Macs. Girl likes things super-sized! Poor thing probably couldn’t see over her massive mouth, and that’s how she ended up nailing a photographer’s foot under her car. I have a sneaking suspicion that her lips actually knocked him out. They’re so huge she had to open her window to make room for them, and crunch! Man down. The incident so upset Britney that she stopped for a moment, started crying and then drove away to go eat a cookie. You know, something she just urgently NEEDS to do in public.
