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 Universal Studios in Orlando with his son.
R.T. fans better read that return policy pretty closely.
