Dianna Agron's new suspense thriller I Am Number Four hits theaters on February 18, and the Glee beauty is making the rounds to promote the highly-anticipated flick. Over the weekend, D and her adorable co-star/boyfriend Alex Pettyfer met fans and signed autographs at the Hot Topic store in San Franciso, CA. After the signing, Dianna took to Twitter saying, "Thank you to everyone who came out yesterday in SF. You were so thoughtful and kind. Always wonderful to be home, even if only for a day!"
