Meryl Streep Identifies Lips Of Alec Baldwin, Sandra Bullock And More On 'The Ellen Degeneres Show'

When you've been nominated for 16 Academy Awards and nabbed two of them, you've had your fair share of on-screen kisses.

When Meryl Streep guested on "The Ellen Degeneres Show" this week, Degeneres put the "Iron Lady" star to a unique test: Identifying the lips of the men and women she's kissed in her films. Unfortunately, Streep wasn't great at kissing and telling.

After thinking Alec Baldwin's lips were George Clooney's, she had no problem identifying her "Bridges Of Madison County" co-star Clint Eastwood's. But when her "It's Complicated" co-star Steve Martin's lips flashed on the screen she said, "That's looks like Newt Gingrich!"

Streep stars in the Phyllida Lloyd's Margaret Thatcher biopic "The Iron Lady" alongside Jim Broadbent, in theaters today.
