Blake Lively arrived at "The Private Lives Of Pippa Lee" premiere in New York City on Sunday looking mighty fine. She showed off her long legs in sexy short shorts and didn't leave much to the imagination with her low-cut blouse. See more photos after the jump.

Last month the Gossip Girl star brushed off rumors she's engaged to co-star and real life love Penn Badgley. Online reports recently suggested the couple was set to walk down the aisle after Lively allegedly accepted Badgley's wedding proposal.

Meanwhile, her beau made headlines for a threesome storyline in "Gossip Girl." A leading parents' group called for the network to drop the sexy scenes. The Parents Television Council (PTC) said, "If this program violates broadcast decency law, rest assured that our members will contact the Federal Communications Commission."
