Los Angeles: Actress Liv Tyler, who is expecting her second child with fiance Dave Gardner, has poked fun at her growing baby bump. The 38-year-old actress uploaded a photograph of herself walking down the streets of New York. In the caption of the image, Tyler expressed her shock and said that she couldn't wait to see her baby. "Oh my goodness look at that bump. So pointy and giant! I can't wait to meet the beautiful little human living in there," Tyler wrote.
