This is just not turning out to be the Tyler family's month.

First the lovely Liv announces she's separated from her rocker hubby, and now comes word that her Aerosmith frontman papa, Steven Tyler, may have checked himself into rehab.

While Tyler's rep told E! News he had no knowledge of the rehab rumor, according to various reports, the 60-year-old artist is currently undergoing treatment for undisclosed substance abuse at Las Encinas Hospital drug rehabilitation clinic, the same facility where star M.D. Drew Pinsky treats patients and where his recent flock of Celebrity Rehabbers attempted to sober up.

Here's hoping Tyler succeeds in becoming a dried-out, albeit not dried-up, rock star.
