Robin Thicke Another Concert Canceled For the Beach

8/4/2014 2:29 PM PDT

Robin Thicke went camping with his son and a mystery woman the same day he was supposed to be performing in Indiana ... and this isn't the first time it's happened.

What was termed a "scheduling conflict" was in actuality a personal day ... deja vu, because he did the same thing back in February when he cancelled 2 back-to-back concerts because of illness, but ended up at Disneyland in Anaheim, CA with his son.

R.T. fans better read that return policy pretty closely.
