I have mixed feelings about this. I guess increased exposure can bring help and awareness.
But if TMZ is just trying to milk their ratings with sensationalism, shame on them. TMZ didn't get a quote from Britney, or provide any additional information beyond what Britney herself has already reported, so they really aren't adding anything to the story. They even scoured old BB TV footage to find this picture, rather than posting anything new. Guess they didn't have permission for that......
You can see the story on the TMZ website here.
I can't even imagine what Britney and her family are feeling right now. I'm sure they would appreciate some privacy while they focus on Tilly's health and comfort.
