NEW YORK — Many screaming girls thronged the Landmark Sunshine Cinema to catch a glimpse of "Gossip Girl" star Chace Crawford at the premiere of his gritty drug drama "Twelve," but it was the NYPD who stopped traffic — to make way for President Obama's motorcade during his visit to New York on Wednesday. The ensuing confusion made it difficult for the cast of the flick to show up for their own premiere.

"We shut down the street for the premiere and for me," Crawford joked to MTV News. "I didn't want any traffic on Houston [Street] and then Obama just swooped in — figures! I mean, I called and invited him and texted him and he didn't want to come. It's just a mess!"

Crawford's co-star 50 Cent was impressed by the way that Obama could just shut down the entire neighborhood.

"It's interesting — the streets are blocked off for a few avenues," he said. "We had to go all the way around to get here, but he's the president."

Zoë Kravitz not only had to battle traffic to get to the premiere, but also the heat and humidity. "We were in traffic for the longest time and I was like, 'What's going on?' " she explained. "I almost got out and took the subway, and the only reason I didn't was because it was so hot my hair would have been out to here," she gestured.

And while the cast was excited to be at the premiere for the Joel Schumacher-directed flick, they know that at the end of the day, the big headline will be Obama's trip to New York.

"It's pretty ridiculous, huh?" Nico Tortorella said. "You're expecting this big ol' premiere and the president walks by and we can't compete! But it is what it is. Welcome to New York City!"
