Justin Timberlake -- I APPROVE of Miley Cyrus' MTV VMA Twerkfest

Breaking News

Justin Timberlake has given his official STAMP OF APPROVAL to Miley Cyrus and her crotch-thrusting, bear-grinding twerkfest at the MTV VMAs ... saying, "It's not like she did it at the Grammys."

Justin appeared on 102.7 in NYC this morning and told Jim Douglas -- "I like Miley ... I like Miley a lot."

"I think she's young. She's letting everybody know she's growing up."

JT also talks about his favorite part of the routine -- and it wasn't the twerking ... or even the drugged-out teddy bears.  In fact, it wasn't even on the stage.
