NBA Star Ben McLemore PRETTY IN PINK! (Rookie Hazing Casualty)

It doesn't matter that Ben McLemore was the 7th overall pick in the NBA draft ... or the fact he's considered a legit future star ... he's still a rookie -- which means, he's gotta carry a "Hello Kitty" backpack around NYC.

We spotted the Sacramento Kings shooting guard on his way to the team bus -- but it wasn't the fact that he's 6'5" that drew our attention ... it was the bright pink bag on his shoulder.

The 21-year-old admitted, "It's a rookie thing right here" ... yeah, no kidding.

Could be worse -- at least he didn't have to shave his head like Friar Tuck, right Tim Tebow?
