Eva Mendes is as classy as ever! The 45-year-old designer showed off her new short haircut to her 2 million followers on Instagram, when one commenter said that Eva was "getting old." The mom-of-two gracefully replied to the troll, saying, "Yes, your [sic] right. Thank god I'm getting old. That means I'm still here. I'm going to be 46 soon and grateful every day that I'm aging."
