Is Jon Gosselin a decent guy after all?!

Last Saturday, the Octodad attended a walk to benefit Autism at the Citizen Bank Park in Philadephia, PA, where he smiled and posed for pictures with fans, as well as the ex Phillies manager Maje McDonald.

It looks like Jon is trying to clean up his image as he is frequently bashed on blogs and shows as being an unfit father for his 8 children.. while his soon-to-be ex wife Kate stays home and runs errands (when she's not traveling around the country wearing bikinis and guest hosting on The View of course).

I guess they need to do whatever keeps food on the table for their Plus 8.. since ratings have been dramatically dropping throughout the fifth season of the "hit" realty show.
