Levi Johnston -- Takes Back Apology to Palin Fam

8/27/2010 5:30 AM PDT
Levi Johnston claims the apology he issued to Sarah Palin and her family back in July was total BS ... and he only begged for Sarah's forgiveness to make Bristol happy.

Levi appeared on the CBS "Early Show" this morning -- where the dude who once posed for Playgirl claimed the only regret he has in life is issuing that apology ... because "it makes me sound like a liar."

Levi had originally issued the apology to the Palins -- in which he admitted to saying things about the family that "were not completely true."
