R&B/Pop Singer Whitney Houston is back in rehab, according to TMZ.

A rep for Whitney Houston says the singer is receiving treatment in an out-patient rehab program for drugs and alcohol as part of a "long-standing " recovery process.

Apparently, Houston checked herself into rehab roughly 10 days ago.

Do you think any of this has to do with her worrying about her daughter, Bobbi Christina's bad press she's received in the news lately?
