Tina Fey looked stunning in her full-length beaded Zac Posen gown at the Oscars last night. She accessorized with diamonds from Fred Leighton. Tina presented the screenwriting awards with Steve Martin and they made a hilarious couple. Tina kept shooting Steve sidelong looks, prompting him to warn her "Don't fall in love with me." We heard Tina's voice in the writing for the skit: the jokes were quite funny.
